machine has a gremlin,most of the time starts and behaves perfectly,other times when u shift to reverse it dies like u turn the key off ,shift it back before it stalls and sits an idles perfectly. Could it be the trans switch or any ideas..thanks

 

Unplug the reverse limiter box black wire to eliminate it from the system.

 

Any wires rubbing when the shifter is moved all the way back?
