PlayStation keeps shutting off and I have to unplug and replug for it to turn back on

Starting a month ago my PlayStation kept telling me it’s overheating then it progressed to no warning instead just shutting off. So as one does I went and cleaned it out. I got the heat sync, removed the fan and cleaned that, everything. It didn’t help at all. Now it’s gotten to the point where it shuts off every 30 minutes to a hour on any game no matter what (ps5,ps4 even streaming services). Also every time it shuts itself off it doesn’t beep three times like it used to it just goes blank, I also have to unplug it and plug it back in after every time it shuts itself off. I know it’s not the outlet and I know it’s not the surge protector I use and my ps5 is in a good place with good airflow ontop of a desk. Any help would be appreciated!
