Preview Playback keeps stopping randomly

I am using Premiere Elements 15 on 2 PCs running windows 10. One an older Dell XPS 9000 and the other a brand new Dell XPS 8900. Both machines have I7 processors, lots of memory and lots of disk space. The older machine has had the same issue in Premiere Elements 14 and 15. The new machine was just setup and is only running Premiere Elements 15.

Both machines pause in the exact same way. After hitting play the video randomly stops. It does not make a difference which clip or it it has been rendered or not. Clicking play starts the video again, and it will randomly stop again.

I adjusted many setting per dozens of discussions I've seen. I tried turning off services and upgrading and downgrading drivers. I removed the RealTek audio drivers. I tried rendering. I tried removing the video card and using the motherboard video only. I tried unlinking the audio from the video and deleting the audio (so only the video played) and I tried deleting the video (so just the audio played). I ran the app as an administrator. I disabled virus scanning. And I even bought a brand new computer (the new Dell XPS 8900) thinking that would finally solve my issue. Nothing makes a difference.

As  richardc40064500​noted in his exact same issue, I also see playback pausing when just viewing a clip in the project assets screen.

I see others have had this same issue and no one seems to have a resolution. It is acting like I am hitting the pause button while the video is playing. The icon switches from play to pause.

Premiere Elements must be pausing for a reason. What can I do to resolve this?
