Unleashed Crashing Randomly

[Moosefu]

While playing singleplayer, the game will completely shut down within minutes of playing. The length of time before it happens is random, but it's never lasted more than 10 minutes. I don't have a crash report or anything because it closes the game and console instantly. There doesn't seem to be any specific action causing it ingame, as it can happen while I'm doing anything, even just standing still and doing nothing.

Console:

Go to options and tick 'reopen launcher after exiting minecraft'. This will cause the launcher to reopen and you will be able to go to the console and use the pastebin button there. When you post it to pastebin link it here.

It's not giving me a log. The window is closing itself mid game without a crash report.

edit: Okay, I'm trying it.
