Intermittent stalling.

87 "Renix" 4.0l automatic trans.Runs for 30 mins then dies. restarts after a couple hours (as if something cools off)? Has any one had this before?If so what could be causing it.TPS,IAC,new.Have MOPAR CPS to replace cheapos.Bitch to change.Should a real CPS fix her ?

Fuel pump dieing? Possibly bad coil too. Have you checked fuel pressure and spark when it won't start? If not then that's where you should start.
