I have a 97 Crewcab/longbed F350 with 7.3 litre diesel engine. While driving slowly(approx 30 MPH) the engine quit. The "Wait to start" light wouldn't come on again. Engine turns over fast with no ignition/firing. Anyone had this problem? What was the fix/cure?

Most likely the cam sensor died, but be sure to check ALL your fuses first, as a blown fuse for the EEC would cause the same thing.
