I have a 2004 F250 6.0 diesel. 131,000 miles. Just started a couple days ago. Sometimes at a stop sign as I press pedal to go, it hesitates and feels as if its not getting the fuel. I then press a couple more times. Then I let off wait a second or two and it works just fine. Today the check engine light came on when it happened. Do you think a service check indicate what the problem is? I never had this type of problem.
