Fuel Issues?

Hi All
I'm fairly new to diesels, I currently have a 92 F-250 7.3 with an ATS turbo. Tonight I was driving and the truck seemed to lose power and when I let off the gas and pushed in the clutch it died. I pulled over but it wouldn't restart. I let it sit while waiting on jumper cables. Then it fired up but was knocking and didn't drive right. The fuel line from the filter housing to IP is clear and shows fuel in it. Is it possible the IP is going bad or does anyone have any suggestions on what I should look at tomorrow? I don't know how old the fuel filter is but im thinking its not stopped up since I see fuel in the line after it?
Thanks

Water can still buildup over time....if this truck has the stock water seperator it will have a clear plastic bowl.....just drain that...see what happens. How many miles are on this truck, whats color are the injectors, injection pump, injector caps? If they are grey...well....sounds to me with the knock, if it sounds like rod knock it could be a injector that is going or is already gone.

This has a screw on fuel filter. its got 214k miles. Im not sure of the color of the injectors or anything yet, this happened after dark last night and today its pouring rain so if it stops im going to go look into it.
Should I just replace the fuel filter since I dont know how old it is?

What clear plastic bowl are you talking about? Is that something on the later trucks?? Mine (88) I think was metal, although I think black plastic was also available. Many aftermarket ones (Racor) have plastic bowls. I replaced it with a one piece filter so no more bowl.

GACowboy, when you filled the tanks, you could have gotten a bad batch of fuel. Its possible the filter is old and clogged as well. Driving along, it sucks all kinds of crap up against the in tank screen, as well as the fuel filter. At some point it gets too thick and fuel won't pass through, so the engine dies. Without the constant sucking, some of the debris falls off the filter and the truck can restart.

I had an issue like that with a minivan I used to own. Some ****** dumped sand in the tank. I could drive around town no problem, but after a bit of highway driving it would stall out. After pulling over and coasting to a stop, it would restart fine, then repeat further down the highway. I was younger and didn't know as much then so couldn't really describe the problem right and it was so intermittent the garage thought it might be a transmission problem. After swapping the tranny, it still happened, but I was off to college at that point. It eventually got worse, and had one or two dead cylinders with clogged injectors before it was finally figured out.

Im going to change the fuel filter tomorrow and see if that helps since I have no idea how old it is, if no change then I will look at IP or injectors?
