Moved to the correct section.

 

Shuts down completely like the ignition is being killed or stalls? I'm guessing the first bit and can only offer that it's something linkage related since it works okay going into reverse. Idling in neutral isn't really a test. I'm guessing that you have been attempting various things but I honestly have nothing specific to help you with. Maybe something linkage related is rubbing on an ignition wire only when going into drive? Sounds things out and a dead engine is the result.
