I have a 1999 ford ranger sport 2.5 four cylinder engine. Engine shuts off at driving speed. Sometimes it does this 3 are 4 times. Will not start back until I turn ignition switch to the off position. I have tried to start it without turning switch to the off position and it will not start. The lights and radio stay on when engine shut off. I have checked to see if I had any trouble codes and I did not.
Does anyone know how to fixes my engine problems?
