I would check the crank sensor. The computer will shut down completely if the crank sensor is shorted.

You should have someone sing a dual trace lab scope, look at the Crank Angle Sensor (CKP) and Cam Angle Sensor (CMP) signals to check quality and sync.
Loose timing chains or broken flex plates can change the sync signal to the Powertrain Control Module (PCM) and cause a stall situation.
Also you should have someone load test the battery and check the cables for corrosion. If the battery drops excessively during startup, the idle motor stepper count can be lost, Powertrain Control Module (PCM) will relearn it while driving.
Clean the throttle blades and adjust minimum idle.
With the air cleaner assembly off, hold the throttle wide open and look down the throttle with a flash light. Look at the lower intake plenum gasket for leaks, oil will build up around the edges and in the corners.
Perform distributor sync adjustment. I hope this helps. tried my best.....

Hi and welcome to FixYa!
This will be caused by a faulty distributor coil. You may want to swap the coil and observe how it goes.
Hope this helps and thank you for using FixYa! Have a good one!

Many Jeep lovers have had to change the computer out because of electrical signaling problems. After receiving the code, the car runs rough and sputters. The only fix I have seen is to replace the computer. You can get them relatively cheap used. Read this before rating. It should clarify a bit for you. Thanks. http://www.jeepforum.com/forum/f13/cel-codes-p0206-p0306-611053/
