My Xbox series S keeps shutting off during 15 to 30 minutes of BF6 gaming.

I don't understand why it does this, but I would be playing BF6 and joined a match and all of and after 15-30 minutes of gameplay my series S completely shuts itself off. Before you ask no message appears when I turn my console back on. The vents, and fans on my Xbox are cleaned and are in an open space so that rules out fan or overheating. I have it plugged into the wall so electrical is not an issue. I've also stress tested my Xbox by playing RD2 and cyber punk and I can play long sessions without crashes.
