A1502 820-3536A working, but turns off after about 30 minutes


Hi, after a bit of a break from board repair due to personal reasons im back at it again! I bought this A1502 13" late 2013 retina which has a super weird issue! It works just fine for a while but after like 30 minutes it cuts out and sometimes won't power up until you let it sit for a while. I already ruled out the battery and thermal issues.
Anyone know what could be causing this?

You need clean ME region.
The PCH is married with its SPI chip, once the board is booted.

Upload somewhere your BIOS, if you cannot clean ME region.
