@Joe K posted:The pickup rollers on the uncoupler may be lifting the engine off the track, and thus it stalls.
If this is the case, you can remove the plastic piece under the pickup rollers (used for electrical isolation) and replace it with something thinner. I used electrical tape, however a very thin piece of plastic sheet would also work.
A pdf of the procedure is included for your reference.
Joe K, thanks very much. Most helpful. I'll try that first thing in the morning....
