If you've ruled out the obvious stuff it sounds like the lift pump. Heard other guys mention the same problem. They put pressure gauge on low press. side and noticed probems with inconsistant pressure. I recently replaced my lift pump and believe it or not it made the truck run better. Easy way to check is by cracking the drain valve on filter housing while cycling the pump. Time how long it takes to fill up a quart container and do your calculations to figure out how many gph your pump is transfering. Adding low pressure side gauge is also a very good idea to monitor your delivery press.

now it seems like the pump. truck does not seem to be getting any fuel past the filter, go figure
