Device keeps crashing, even when I boot Batocera from SD

[B3N313]

My Powkiddy A13 keeps crashing, I flashed Ruka CFW onto it a while ago, then this problem started.
I did not use the device anymore, now I flashed batocera onto an sd card and it boots up into batocera, but I have the same crashes that started happening when I flashed Ruka.

What happens is, the device suddenly turns off, in-game or in menu. I can barely do anything with the device before it shuts down.
I have one of the later revision A13, with the second version of the motherboard.

Could this be due to overheating, what changes did Ruka do the the device that that are still persistent when I boot into Batocera?
Did any overclocking take place?
