i got a 00' F250 7.3 yesterday i drove about 85 miles down the highway and out of now where it started missing and got down to about 35 miles an hr. i had it towed back home and when it got there it ran fine. i didnt mess with it today but it started u fine and ran ok. i did not have a CEL Please help me (its all stock)

 

change the fuel filter

 

filter was changed out about 2 weeks ago. but im going to change it out again. any other suggestions

 

I have seen fuel pumps on 7.3 do this and also if it is a high mileage truck I have seen the strainers in the fuel sending unit plug and do this exact thing. IE starve it for fuel after running for a while then after not running for a period it would run fine...... Just something to check.
