Default missing bad

ok heres the deal, i have a 6.5 with the electric pump. ia am a cummins guy so i know very minimal about the 6.5. the problem is when the truck is at idle it runs smooth. as you start to drive it does good then it begins to spit and sputter and feels like its gonna die. then is clears up and runs fine. i dont think its a bad injector because it doesnt miss at an idle. like i said im a 12v cummins guy.
