Ps5 turning off randomly

So like the title says my ps5 keeps turning off randomly acting like I’m unplugging the power cord and it’s never acted like this before until today. Not sure if this info is helpful but this past week until today it was not in use and not plugged in and the week before I had it set up at my girlfriends apartment and there were no problems there. The ps5 is horizontal and I was playing destiny 2 when they were happening and i apologize for the flair i couldn’t find the support one
