After Effects realys on your RAM for previewing. A preview of 7 minutes requires a big amount of RAM at full resolution. What you can do is to change your composition resolution to half or third to get more seconds for your preview. Also, you can preview smaller areas of your timeline using the Work Area ranges. Befor changing resolution I suggest you to purge your cache in Edit > Purge > All Memory and Disk Cache.

Then enter into the composition settings, change the duration and move all your layers to the right. Composition > Composition Settings. Make sure you are not zooming into your timeline.
