Why does my Verizon tablet keep greying out and crashing?


AC Question

I've had the Eclipse tablet for a while now and have never had a problem with it crashing on me. Sometimes my apps freeze if I have too many open but its a rare occasion.
Yesterday morning I was on it as usual and had no issues when suddenly I was listening to soundcloud yesterday evening when it suddenly stopped and crashed. I restarted it and went back to what I was doing when everything froze and it slowly faded to a glitchy grey screen and cut off.
It's been doing that since last night and won't stop.
What do I do?
