What Causes A Diesel Engine To Run Backwards?

A hot patch causes the fuel mixture to ignite too early, resulting in ‘running on.’ It just pinks and keeps going in the regular direction when running fast enough, but just before stopping, the pre-ignition is so early that the piston direction is reversed, and the engine spins backwards and stops.
