yeah,.....post some fricken video already!!!!
but naw, its sounds like its one of those simple gremlins that drive you nuts for about a week. And then you figure it out after spending $150 bucks replacing what you thought it was.
does it give you a flooded smell at all when it happens?? too much gas going in still and drowning the engine?? vacumm?? timing?? those are my guesses. MAF's are usually good or not. could try swapping a MAF with a friend and taking it out for a little test run??
good luck
