This seems to be happening once an hour or so. The bars will come up on the screen, it freezes, and about 10-15 seconds later it'll shut off and reboot. Has anyone seen this before? I tried to search for the issue, but I'm not really sure how to describe it well enough to search. Any help would be appreciated.




 
This is crazy... I have the same Macbook and mine does the same thing!! I too changed out the RAM to 16gb a few months ago.
I'm also looking for a resolution... if you find anything, let me know? I'm looking too!

While odd, mine hasn't done it the last 2 days. The only thing I did was run a Hardware Test. It didn't show any problems, but this hasn't happened since. Maybe just a coincidence. https://support.apple.com/en-us/HT201257

I'm sure as soon as I type this it'll do it again. lol
 
If your machine is a 2012 13" than it's the logic board. You can force the issue by flexing the top case or knocking on the keyboard in the area of the 3, E and D keys. This will confirm the issue.

Tried that and couldn't get it to happen again. Hasn't acted up the past 3 days.


Edit: So much for that. Just happened again.
