2009 Dodge 3500 4x4 6.7 stutters, shuts down completely and turns back on while driving. Done some research and someone suggested it might be fuel control accuater and that I should flush it out with WD40. I did that and the truck ran flawlessly for about a week. I changed the part out and immediately it started doing it again. I changed the fuel filter about 7 months and less than 3000 miles ago. The check engine light doesn't come on and there are no codes. Any idea's or even point me in the right direction

Check your lift pump for correct and constant pressure. Ideally, you need to have a gauge for this and can see when it shuts down...
