I think it could be a top case or power switch issue. If you want be sure, remove the bottom panel, disconnect the top case ribbon cable from the logic board then start the machine directlement from the two power pads that should be located near the top case ribbon cable socket. If the machine start and run without the issue then you know the top case is faulty.
