The Chrysler dealer has a scanner called the Star Mobile that can be connected to the car while you drive it. There is a "record" button to press when the problem occurs. That will start recording a sequence of events that can be played back later at the dealership. Because the sensor data goes through the unit's built-in memory, the recording actually begins a few seconds before you press the button.
The mechanic will look for clues from the recorded data. There might be a glitch in a sensor that is involved with calculating how much fuel goes into the engine, or the clue might be found from a sensor that reports how the engine is running after the fuel is burned.
The manufacturer's equipment always does more stuff than the aftermarket equipment used by independent repair shops. The Chrysler DRB3 scanner will show things and perform functions that other scanners won't.
