In parts list above # 14 is fuel pressure regulator. When engine quits, do you here the fuel pump running? If you remove line at the fuel regulator , is it bypassing fuel back to the tank?

Not sure if bypassing but pump is running.

If regulator is defective, the fuel my just be going back to the tank. Have you checked the fule pressure after the fuel pump?
