Hi,
I'm not sure which engine you have. Is it a 2.3L or 2.6L? What you described sounds like a weak connection issue. Are the battery terminals tight, clean, and free of corrosion? Also, have you checked grounds such as the one to the engine from the battery?
I attached a wiring schematic below of the 2.3L starter circuit so you have a reference. Check to see if there are any wiring concerns.
Let me know.
Joe
