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 Jeep 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.

Hope this information helps, and let me know if you need more assistance with this.
