Engine loses power at first, check engine light comes on. This is when the engine is pretty warm from traffic and climbing a hill. Last time no check engine warning ... engine died and would not restart until cooled off.

Irratic/poor/stumbling engine performance... Would not rev above 2000-2200 RPM while "trying" to drive. Upper bearing failure in distributor... caused crankshaft positioning sensor to send erronous signal to ECM. Replaced w/ new distributor.
