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. Since you have already replace the PCM, your problem is most likely the carank or cam sensor. Most common is the crank sensor, so replace that one next and PLEASE use a Mopar OEM sensor. Some of the aftermarket ones are junk. If it still acts up, go with the cam sensor in the distributor. I am 99% sure that this is the problem.

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