97 7.3 Fuel filter light, truck dies, runs fine.

Hey guys, I just picked up a 97 7.3 a few weeks ago. Up until yesterday the truck ran great. Good power, no issues, and it was running good. Yesterday, I got fuel, drove a few miles down the road with no issues and turned the truck off. Start it up about 15 minutes later, and it started up fine no issue. About a mile down the road the fuel filter light came on. About another mile down the road, the truck starts losing power and starts to "knock" (that's the best way I can describe it) and really bog. Pull off the side of the road and it dies. I get out, check the fuel filter, it looks good, put it back in, and it starts up but runs VERY rough and is almost impossible to keep running by itself. I eventually got it running about ten minutes later, and it ran like there was no issue for about 3 minutes down the road and then the same issue. I had to repeat this process about 5 times to get to my shop and diagnose it further.

Anyway, I changed the fuel filter, and on the ride home, it drove fine. No fuel filter light, no lack of power, nothing. This was about a 45 minute ride home, and I figured the filter was the root cause of the problem and called it "fixed". Well this morning, on my way to work, the truck did the same thing. Light came on, loss of power, truck dies. Same deal, about ten minutes later I get it running, am able to drive it about 2 miles and same thing again. Wait ten minutes, get it going, and I am able to get it home. Changed the CPS, just for shiggles, let it sit all day, and then I took it for a ride for about 10 minutes and no issue. I'm stumped. I did quite a bit of reading around the interwebz and I am coming up with a few possible solutions. I am planning on changing the fuel pump, and I was wondering if there is anything else I should look at.

Sounds to me like you've got water in your fuel. I got fuel out of a rural station once and had the same symptoms. Once I ran through that tank, I haven't had that problem again.

I think you could add something to the fuel to get ridbof the water. But if its water water in fuel light should be on not fuel filter.. only timr I saw a fuel filter light is when my pump went. I deleted my sensor since then due to it leaking. So. Just my .02

I'm having a very similar issue, on my front tank the fuel filter light comes on and about a minute later the truck runs rough like its out if fuel. So I changed the fuel filter, and put some injector cleaner in, still does the same thing. When I switch to the rear tank it runs fine so I'm assuming its bad fuel but I'm curious to see if its something else, or if there's anything to remedy the issue.

Do you know if the screens in the tanks were ever changed? I picked up my 95 psd in June and had similar issues. Dropped both tanks and the screens were all broken up in both tanks. Before the repair I was only getting to use about 14 gallons out each tank. Now I have 19 available in the front and 17 in the back. The suction hose had parts of the screen clogged in it from the front tank also.
