Most people are going to need more info before a diagnosis can be made. Describe what it does and under what conditions. My first blind guess would be EGR valve related. Give us some more info and some of the better gurus around here will surely have an answer for you.

ok I was driving down the road at around 70 mph and for a seconed i thought the fuel filters were trying to plug because the tac started droping off. then the truck just shut down. I changed filters and started it. it ran for about 30 secondes to 1min and died. if you loosen the fuel filter on top of the motor it has extream pressure. put it back on it will start then die. if you do not take the presure of the to fuel filter it will not start

CJ --- might be an idea to fill in your signature. Then the techs will know the year,any mods youv'e done and so on and so forth. Might be the cam sensor, But I'm not a tech. Good luck.

I can't help you any more than to keep this thing bumped up until Marc, Jon or another tech can see it and help you out. It's not a symptom that I've heard any others speak of on here.

I was woundering if it was a fuel presure ragulater
