It sounds like it could be a tether connection issue. Do you have the ability to run it conventionally with a variable voltage transformer?

Had almost the same thing happen to me yesterday with my new Railking Imperial Big Boy (PS3). It had been running just fine, and all of a sudden it started stopping on slight curves, if it was running slowly. Completely shut down every time!!

Took the "wireless" drawbar off and put the multi-meter on the pins, to check for continuity. Power was coming into the drawbar from the loco pick-up rollers, but was not getting across the drawbar to the tender end on one set of pins.

Got the soldering iron out and re-flowed the solder on the suspect pin, and checked it again for continuity....all good!!

Big Boy is up and running again faultlessly.

Check the "wireless" drawbar for a faulty soldered pin connection.

I'm going to have to dig for one but I will try thanks for the idea.

thanks Buco.   I may have to break out the tools to do just that!

Make sure you seat the drawbar fully.  Also do a reset.    G

I was looking at the manual, and it seems to cover a whole range of issues in setup and troubleshooting that if you follow may lead to the problem. The drawbar was also specifically pointed out.
