Fuel system/air intrusion or possible your fuel tank siphon.
How much fuel in the tank(s), and when was the last time you changed the fuel filters?

If you havent already done so (sorry ive been out of town) fill the new filter with 50/50 ATF and Diesel Kleen or the like. Helps to clean out the fuel system. If you leave it dry youll be cranking forever to fill it up and prime the system.
BTW a oil filter wrench that fits the oil filter will also fit the fuel filter.

ok got the thing primed back up let it idle for about 5 mins done perfect now its doing the same thing it was it will start runing rough an then die. i cant figure out what it cold be other than a fuel issue. guess its time to get the brakes unstuck on the f150 an mess with it a little while an take the f250 to the shop

What does the fuel look like in the bowl now? Any better or still nasty? If nasty, you have to drop and clean the tanks.

X2 heath. You very well could have algae in the fuel. If you do have it (usually seen by black goo in the fuel filter) you need to drop the tanks and clean them then run a "shock" level of Biobor JF to kill any remaining algae. Also keep changing the fuel filters until they are clean. http://www.filterbarn.com/ has the best prices on filters (i run International fuel filters from there)

yeah napa is a joke. I ordered 12 IH filters for 9 bucks a piece and got free shipping. To say the least I have a few spare filters.
Also if you didnt already know, put some oil on the o-rings when you spin her on.
Back to your problem... I'm going to guess its the IP but I could be wrong. I have a feeling though that water clogged it up. Did you try running the ATF/Diesel Kleen through the filter? Maybe that will help clear it up
