94 Acclaim 3.0L missing and dying

MAP sensor error message can be caused by vacuum leaks, sensor itself, EGR problems including sticking, leaks, plugged ports, etc.

Unfortunately, the intermittent nature of your problem makes it hard to spot.

Inspect the engine for places where vacuum leaks might be occuring. Check out the EGR and do what you have to do to implicate or eliminate it from the problem.

My sentiments exactly.

EGR in its entirety (three parts IIRC) was replaced with factory parts early 2007. (Not that it's not worth checking anyway, just unlikely.)

I had a Dodge that was missing once, but it turned out I just got drunk and forgot where I left it.

I know a guy who did /exactly/ that once, many years ago!

He had an '80s Dodge pickup. We had gone bar hopping in my car, leaving everybody else's cars behind. By the time we went back to where we started from, he was so hammered he forgot where his truck was (on a side street somewhere) and ended up having to take a taxi home. Which, in retrospect, was probably a good thing... He eventually found it the next day, he and his wife cruising the streets in the area for an hour before spotting it.

try a fuel pressure test

Probably worthwhile, but the fuel pump is less than six months old.
