Perplexed
This post is from a neophyte to forums and i have two issues that have been ongoing for over a year. They only occur occasionally but can be disconcerting when they do occur. Would appreciate any guidance.
Vehicle<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com
fficeffice" /><o
></o>
2002, F250 super duty, 4 WD, 7.3<o></o>
Issues<o></o>
1. Under pulling conditions on steep inclined I experience a power loss where engine almost stalls. After a few seconds I regain power after letting up on the accelerator. I have changed filters and rebuilt drain valve on fuel filter bowl. Old one was leaking.<o></o>
2. On rough roads engine light will come on and engine will stop. Occasionally engine will run rough. So far it will start again or run smoothly on its own.<o></o>

For both problems the first thing to do is to get the codes read by someone that has the right scan tool. Without the codes all anyone can do is guess. Such as the HPOP guess. There is no basis for that guess without knowing the codes.

Sounds to me like you got it scanned with a code reader that's incapable of reading more than generic codes. I'm going to send this one down to the 7.3L Powerstroke forum, you will probably find more help down there for your specific problem.

We had a lady on here one time that had the problem going up hills. She had all kinds on things done at dealers and it didn't cure the problem. For her it was the in tank mods that cleared her problems. On rough roads. Maybe a harness at the valve covers. Again easy checks but guesses. You really need a special scan gauge to read these diesels. The intank problems won't come up on a scan.

If this sounds familiar, do the Hutch mod immediately:
8-5-12 Driving from Idaho to Sacto, van started losing power uphill. We would pull over and wait ten minutes and drive up the remainder of the hill and continue until the next hill where we would repeat the process.

Those would be my guesses too.
