why does my dodge shadow only stall when warmed up and not restart till cool?

r problem was they would stall for no reason. It did not seem to matter how long the car was driven for, or the outside temperature. You would be driving along and it just stalls. You pull over and wait about 5 minutes and it starts up. You don't have any problems after that for at least a couple of days, or weeks. We too went years before we actually figured out what it was. It was suggested by somebody on the internet to change the engine pickup sensor (located under the distributer cap). We did just that on the Shadow first, and have not had a problem for at least 3 months. The car is being driven every day, and it has not given any problems after changing that sensor. We then changed it on the Dynasty and that car has been fine ever since. The sensor on the Dynasty was expensive (about $300 CAD), but the sensor on the Shadow was cheap ($50 CAD).
