I have a 2001 7.3 that is having trouble running after about 30 miles . It won't run and has to be shut off -after about a 30 minute rest it will start idle fine and run for another 30 miles. The fuel filter has been changed - this helped but only minimally. A code reder shows no fault codes. Any help please.
It's not the CPS - put one in today and it does the same thing. When it is first started up when cold it runs like a champ and has a lot of power .As soon as it gets good and warm 15-20 minutes of driving it loses power and starts to diesel real bad. The check engine light never comes on and it shows no fault codes.
