Yeh, definitely the fuel pump module, had the same exact problem happen to me ths weekend, but i went thru the hassle of changing the filter and then the pump and finally took it to a ford mechanic and it was the fuel pump module. got it back today and its running great

 

i am glad i didn't bother dropping the tank to change the pump, what a hassle, i really think the floor of the box should have an access hole to get at the pump, it would be so much easier.

but what a stupid place for these modules, under the truck like that on the frame, of course the salt and water is going to get in there, would have been much better to have it mounted under the hood!
