My game keeps spontaneously quitting

Since the last update my game has started spontanouesly quitting every few hours. I don't know what is causing it, but it's giving me insane amounts of rage. I'm saving as often as I remember but I don't know how to fix it. I've removed all of my mods and it's still happening. 
Anybody else having this issue. It's driving me insane. I don't know how I can keep playing the game like this.
