truck sputters

[99 7.3]

gotta question for ya all. my truck quit on me a while ago while i was going down the road. then it wouldn't start, but finally did, then quit again, but finally started up and continued running. the truck sputters and acts like it is missing on one cylinder sometimes. i replaced the cam sensor, but it started up again. i'm going to check the codes today when i get home. just wondering if anyone has had this problem before. going to start it up and pull and check the wiring harness to see if that might be the problem. truck has 168000 miles on it w/ 6 position 4 bank bully dog. any ideas would be great thanks

May be an injector, pulling codes may help.

if the check engine light comes on when acting up ,leads me to think you might have wiring harness under valve cover coming loose, always check oil level and quality

check your fuel/water separator. mine had the same problem cause there was a build up of gunk beneath the fuel heater in the bottom of the housing. all u have to do is remove the housing and clean it out and it should start
