i made a post about this before, in that case i solved it by replacing trackpad, io board...but now ive got two of these with the same issue. i replace trackpad and io board, and they are still shutting down ramdomly. i dont have any idea where to check, since its such a weird issue...

Test the board alone, without TP/KB, nor RIO flex, or other device connected.
Use an USB device to confirm activity.

All the voltages come on, including VCORE?
PLT_RESET_L goes high?
Any history available?
