It sounds to me one or both could are bad,when they heat upit loses power check that it's either 1234 depends if its 8 cylinder or not.


Your coils check em,that's what it is.

Have your catalytic converter or all (if more than one) checked on the exhaust system. If clogged, vehicle can't breathe.
