I left the computer on all day today. This time, first time in 8 days, it did not shut down.

So I opened  Console, 1st time I ever used it!
I found this :
2015-08-07 11:53:50.000 AM kernel[0]: Previous shutdown cause: 5
The previous days were not logged in the console window.


Well, we need to see what the console says (actually see if we can figure out what happens BEFORE the shutdown.

SO, somewhere around 11:52, thats' the lines of the console we're interested in.

(Remember, you have to clear the word "kernel" and then you can see what happened around 11:52)

Cause 5 (from what I can tell) a normal shutdown; some shutdown types are due to things like excessive heat.

Let me know!
