Yes Same problem 03 Diesel Mondeo Flashing glow plug Light. Stuck in traffic lane 3 M6 no engine! Moving to hard shoulder on starter motor when engine fired. Next time at a roundabout,no engine! Moved on starter motor to safe place, called AA. Engine started again just before AA arrived. Explained situation AA followed me home and plugged diagnostic computer into socket under dash drivers side.There it was cam shaft sensor fault recorded twice. Looked in haynes manuel found where the sensor was (front of engine just below injectors.Went to local Ford Dealer bought a new sensor for £14 . It took about 10 minutes to fit it (one 8mm socket,wiring plug is a bit difficult to remove because of locking dimple on underside ) Problem solved car is running very smoothly.
