Ok so driving around normal my trucks fine idles fine everythings fine. But if im coasting around on the freeway or city streets and i floor it or give it alot of diesel it seems to sputter or stutter before it kicks in n goes almost like its not getting diesel i dunno if its the fuel filter or what ????????

When was the last time you changed your fuel filter?

not sure exactly my truck only has 9000 miles on it. on my dash it says the fuel filter is at 50%...

Mine did something similar, although my fuel filter life was at 53 or something %, then the truck acted like it wasnt getting enough fuel and I checked the filter % and it was at 0. I personally dont trust that gauge.
