Why does it only turn off when I play injustice 2

Hi there,

I’ve been having this problem for about 4-5 months now where my PS4 turns off without warning randomly when I play injustice. When I first got the game it went perfectly fine but after about 2-3 months it turned off, my brother and I didn’t think much about it but later it started doing it frequently especially when we opened mother boxes. Sometimes it would turn off 5 mins after we stared the game and sometimes like 4 hours later. We tried not playing it for a while and it seemed to be helping cause we managed to play for 2 hours just fine and then we turned it off. And it was fine for about a week but then again it restarted and we were starting to lose data and get annoyed. I’ve tried many things on other forums but none of them have anything to fix something like this because it literally only does this with injustice 2 everything else we can leave on over night and it’ll be fine.

If anyone has even a clue about what we should do please feel free to help!
