2Lane,
I had this same problem too, after a pump/pmd was replaced by the dealer.
Definately go down to Autozone or your local parts store that has a scanner. Get the code so that you know.
But, also check your grounds!!! My grounds that go to a stud on the intake manifold back by # 8 cylinder had loosened up-big time. Once I tightened my problems went away (9months)- I also has some other symptons as it would die and the Service Throttle light came on...my volt meter, oil pressure gauge were behaving erratically.
Bad grounds will do crazy things...check them before you start chasing parts.
