Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome to just answer! There are 3 common causes for this. 1 a failing crank shaft position sensor, 2 a failing cam shaft position sensor, and 3 a failing PCM (engine computer). Either one can act up when the engine warms up. Do this: try to get your Durango to an auto parts store like AutoZone and ask them to connect their scan tool to your vehicle and check for any trouble codes. If there is a code for "loss of crank sensor signal or cam shaft sensor signal" then have the appropriate sensor replaced. If there are no codes at all, then suspect a failing PCM and have it replaced. Most auto parts stores will connect their scan tool for no charge to you.

Good morning! Just checking to see if you received my answer last night. Let me know,
Sounds like it is indeed a PCM. You can get a refurbished one for around $200.00 - $250.00. Very easy to replace. Just have your mechanic order one that is pre programmed to your VIN number. Then it can be installed without any need to program it.
I hope this helps, and please don't forget to rate my service when you get a chance!
