You've eliminated some variables:

Fine on test stand. That means everything is fine in a straight line.

Problems on layout = curves are probably causing some issue. That would point to the drawbar connection.

I bet the drawbar connector on either the locomotive or tender side doesn't have enough slack. That is probably causing either side to lose connection and then come back. Pop the shells off the locomotive and tender to make sure the wire harness has enough slack to move with the drawbar. I bet that solves the issue.
