PCM - or more correctly in your case, the Engine Control Module, is what tells the engine what to do, based on what it receives.
Your cam and crank sensors should have posted a trouble code that could be read - no code, generally, no problem with them; however, could be intermittent.
That should give a trip failure, but that is only accessable with a DRBIII scanner.
Best guess would be a faulty connection somewhere, start with the ECM connectors, remove and inspect & clean, then the two engine connectors above; pull all the relays in the block and reinsert - you could change them around as well, perhaps change the symptoms to a different area if it is a failing relay.
goal - have one of my parts on every DI car:biggrinfl
