Yeah, had that happen with my old GP38 a couple months back. One evening it was hauling freight like a champ, next morning it was stone dead. First thing I did was pull it off the track and test it on a short piece of powered flex track—nothing. Ended up popping the shell off and found one of the pickup wires had actually come loose from the truck.
Quick solder job fixed it. While I was in there, I cleaned the wheels and contacts just to be sure. Been running smooth ever since.
