Black Screen of Death Maybe!!

So I start the Steam Deck up after not playing for 5 hours or so. Everything boots up correctly, the game loads, and the game starts up. However, a minute later, the screen goes black while the sound is still working. Power off, the power on everything is playing normally, one minute it does the same thing. It does this up to 5 times before I can get it to work fully. Is this the Black Screen, Oh Death?
