Hi I'm looking for some insight on to a completely random issue I just had. So I replaced the plugs and wires, both belts, lower engine mount, a tensioner pulley, and an idle pulley on my 99 GTP. About a week ago on my way to Oreilly's, my car randomly dies. I still had power, just wasn't running. When I pulled over the car would turn over for days, but wouldn't start. We checked all the connections with the coil packs and plugs and they checked out, then took a plug out and checked for spark...no spark. Did some research and it sounded like either the ICM, or the crank position sensor. I wasn't sure where to start, so I disconnected the battery and reset the PCM hoping for a one time start with no such luck. After 2 days of sitting with no power, I did get it to fire, but it died about 4 seconds later after running rough like the timing was off. The ICM had power to it, so I went the cheaper route and ordered a crank position sensor which arrived today. For the sake of trying, I went to start the car and it fires right up and drives 20 miles with no issues. With multiple restarts successful, I am completely baffled as to what could have cause the issue.
