truck dies like its fuel is gelling butttt?

[07powerstrokebosss]

ok so ive got an 07 and on the way back home from plowing it started to want to die at high speeds, the fuel filters are near new a little over 1000 miles on them and i was using fuel treatment rated for -40 and its only in the teens... ive gelled it up before and its acts like its geling up but i even tried different fuel treatment and topped my tank off with fresh fuel...
the trucks got 137000 miles on it i run rotella synthetic oil with hot shot secret addative,... any how when it started to die i thought it was geling so i took the filter under the hood off and put a little addative in and put the filter cap back, the truck ran fine for maybe ten miles then started to die off slowly again it just lacks fuel when i pulled the filter (after it dieing the 2nd time ) i noticed that the fuel filter housing wasnt as full as it was the last time i had the cap off, so any thoughts or ideas? as of now its sitting in the dealers lot to get scanned tomorrow....

Either the pump underneath is going bad or your fuel is gelling. Pouring additive in the top filter isn't going to do much. You might want to double your additive and see what happens.

alrady tried that and got the truck to run all the way back to my local dealer (25 miles) but i had to go about thirty to make it there...is there a fuel tank pump? if thats the issue will it come up on a code reader?

and when i was sitting at idle i swore i heard air or some wistle under my truck prior to the dieing.... i suppose that was my dieing pump not just my imagination

you might have an injector problem of some sorts. Read thru the oil thread in my signature it has some info on cold starts. When was the last time you changed the oil and what oil are you using?

Picked it up yester day from dealer bad FICM I've had the truck two and a half years and its never started as well as it does now, and I got the parts for cost =) i thought it just was born a cold startin son of a bi##h but guess that thing was outta wack good for a another 140000 =)
