It's DCC "ready" or "equipped" right? Would a bad decoder or loose dummy plug cause an issue like this? I know you run it on DC, but a DCC "equipped" will have it's decoder and a "ready" model will have the dummy plug.

If either direction works I doubt it's a wiring problem because the motor turns, I don't see how reversing the polarity would change anything.
However, if the loco does have a decoder it may have developed a glitch: Resetting the decoder to factory settings would probably fix it.
Bill, try taking the loco to a shop with a DCC system. In most decoders, programing CV8 to 8 will initiate the reset.
Otherwise there may be a mechanical explanation, perhaps something has come loose or broken off and is now rubbing against a gear?
