2015 macbook pro 15 randomly turns off, but Windows runs fine

All of the sudden, the screen turns off and the computer shuts off completely, usually within 5-15 minutes of use. I formatted the Mac partition, and reinstalled MacOS, and the problem still persists. However, using the Windows partition, I dont have any issues. Any idea of whats going on? I'm in a remote Pacific island so it would be dumb for me to send it somewhere if its a simple fix.

I also noticed that the MacOS turns off quicker the second time around. IE, I can get 15-20 minutes before it turns off, and then if I tried to turn it on right away, maybe only 3 minutes.


I have not had any issue on the Windows partition, and even during the recovery mode format Mac partition and reinstall Mojave, it was fine for that process as well.


Ive reset SMC, NVram/Sram as well. Only thing I havent done is format the windows parition.
