[QUOTE="DOWNS, post: 439149, member: 21038"] Check the wiring harness for the crankshaft position sensor where it goes over the back of the intake manifold, the harness can chafe there and ground out at random. But really what you're describing is a classic symptom of a bad sensor. When they get hot and the internal pieces expand the circuit opens up, when they cool the circuit closes again. Which means that checking something like the crank sensor with a multimeter can show a good sensor but it could be failing when hot. I know you said you've replaced the Crank position sensor but if you used anything other than MOPAR, it's not unheard of for them to be bad out of the box. Even a MOPAR branded one has a possibility of being bad. [/QUOTE]
