It looks like this was my problem too. For one last try, I put the roller pickups back on and switched it to 3-rail and its working now. I must have a bad switch.

Most of the time, the switch is stuck and/or not thrown fully. I find those easier because I'm two rail. It creates a dead short when thrown or stuck the wrong way for me. Maybe 3x total now out of many, many engines.
