I recently repaced tps on my 02 dodge Durango and i have expecting olot of other problems. It started with ecm over heating and engine shutting off, i so far i have replaced tps,ecm,cam position, now truck cranks up idles for 30 seconds and shuts off as if it was swithed off. Any help would be greatly appreciated as i am at my witts end with it...

 

If it won't start right back up, check and see what you are missing, spark, or fuel.
