Source and Program Monitor Freeze After few minutes

FIXED! The answer for me was to open premiere immediately hold down Shift+Alt+Windows to reset preferences and cache plugin. it brought up a prompt asking to reset those 2 things, hit yes. BOOM working again, for now...

probably your media files and project files are living on the same drive as OS and Premiere, try moving them to a seperate drive

I recently experienced this same issue - I have tried quite a few possible solutions and believe the GPU correction (step 3 from Real Quiz) did the trick for me. Here is the quick version of what is outlined in that article: 

1. Disable GPU usage during playback.  Navigate to File>Project Settings>General and set the Renderer to Mercury Playback Software Only.

2. Go to Sequence>Sequence Settings and uncheck the Composite in Linear Color checkbox.

3. Disable any additional video output by going to Premiere Pro CC>Preferences>Playback and unchecking the Enable Mercury Transmit option.

Best of luck to everyone as they work to get Premiere back up and running!

I am having the exact same prolem with the addition that when I close it it takes about 15 mins because it stops responding then finally gives me the option to close program. 

Hey bro
Even I was facing the same issues 
Finally what solved my problem was that I imported the file from the original place from where I had previously stored

I orignally had stored the mts file in my D drive from the D drive I copied the file to E drive and was importing the file into premiere from the E drive

I was facing the same issue like you

Tried clearing the cache 

Finally got to know something and now I imported from the D drive and its fine now

Same issue.  And I'm seeing it happen during thumbnail view and list view; thumbnail views are still fine and responsive even.  It's the program monitor window that dies.
I'm assembling clips together, scrubbing through my source clip, dropping them in the timeline.  Fine.
Double click thumbnails to open a new source clip.  Fine.
I think there was audio during this clip.  Click on the "Drag audio only" button to check the audio waveform.  Fine, BUT!

Now the video portion of the program monitor window is frozen.  No matter what I do where I go I got nothing.  Even exiting the program doesn't work.  I need to "End Task" to close out.

So I try again.  This time avoiding the audio waveform.
All is good but I have another clip I want to check for audio.  But now I have to play it normally and listen for dialogue.
Click on play...
Frozen, nothing works.  Have to End Task to get out of it.

Third time through.  Going though files in list view.  Watching files 1 by 1, pulling clips out as needed.  Try to open the next file.  Suddenly frozen, not working anymore.  If anything the problem happened when I clicked out of Adobe Premiere to scroll up the webpage I have in the browser on my other monitor.  Click back to Adobe to watch the next file.  Frozen.

This problem is making a 6 hour culling section take my entire 4 day weekend.  I'm researching Adobe alternatives now because this is basically un-useable.  Please fix this soon or I'm jumping ship.

PS:  I tried the steps "Real Quiz" mentioned and they didn't work.

I just had the exact same experience and after a couple of days of scouring the internet, these forums, and running some experiments myself, I seem to have fixed it.

Here the quick list of what I did.
1. I reset the preferences file and plugin cache by holding shift+command (Mac) while starting Premiere Pro.
2. I had recently installed a couple of novelty fonts for a project that I thought might be corrupt (and was preventing Illustrator from opening the AI file I was working off of) so I deleted them. Illustrator works fine now, but I'm not sure if it had any impact on Premiere Pro.

3. On the Project panel I changed the view from "Thumbnail" to "List."

4.  I followed the GPU settings steps from this article:
https://blog.frame.io/2017/11/13/common-premiere-pro-crashes/
(There are probably some other good steps here, too.)
5. But the thing I did that I believe really fixed my issue was address a couple of .MOV clips I downloaded from Motion Array and was using in my project. I suspected that one or some of them were somehow conflicting with Premiere Pro. The issues you described started happening around the time I added those short clips to my project. So I opened each clip in QuickTime and when QT "converted" the file in order to play it, I saved the converted version of the .MOV file, deleted the old one, and re-linked the clip to the converted version when I opened the project in Premiere Pro again.

I wish I would have done each step individually, testing my project and the freezing software issue after each step, but I didn't have the time or patience so I just performed all 5 steps all at once. But I really believe it was the .MOV files that were hanging me up.

Ryan,

What happens with a brand new project? Can you test it out for us?

Thanks,
Kevin

Further information:

Pressing K will play audio from either the source or the program but video is frozen, as well as the playhead in the timeline and source or program is also frozen. Audio still plays from both.

Just uninstalled EVERYTHING adobe from my PC and restarted pc, manually deleted the rest, restarted again, installed CC and Premiere. Same issue but didn't even give me 10mins of working properly.
