PROFORM 835QT Stops under load, then Restarts.

edited January 6 in Treadmill Problems
Treadmill runs with no load, stops with load. When it stops, the motor and walking belt stop.

I have already replaced the walking belt and lubed it. Not it.

The motor belt isn't tight or loose.

I have tested the motor flywheel with a foreign object with downward pressure and it stops, doesn't slow down.

I checked the motor brush and check for demagnetization, looks good.

Do I need a new motor or controller? uggh... Both are $200 for this machine.
