If you have no link [no communication ] with the pcm when this happens I would guess that it could be either the pcm relay or the pcm. if the pcm relay is bad no power will get to the pcm causing it to not communicate. since the relay is much easier and cheaper I would start there. It is a standard full size Bosch style relay you can get one at any parts store.
