I recently had a CEL code P1457 and while driving at times the car will shut off on me. I will pull over put it in park start it again and it's good like nothing never happened. I had changed the Shut Valve solenoid 2 wks ago and I never got the CEL on the dash again and the car never shut off on me for about 2wks until today my car was shutting off on me while I was driving. Doesn't matter if I'm doing 80 or 25mph the motor shut off with the radio still playing. I'll give it a few attempts to start it will just turn but not start, continue again and it will go then shut off in a patterned. What can be the problem, I don't have a CEL??? Is it my fuel pump??? Please HELP
