Not likely injectors then. Change the filters, should likely resolve your issues. Make sure you use OEM, there were a ton of counterfeit OEM painted/branded being sold on Amazon a short while back, caused no end of problems, including stalling and failures to start.

I know this sounds crazy, but take a close look at your truck's batt connections, anyfuses and the cable connections. And the battery to body ground. And wiggle the fuses. They're probably all ok, but it only takes a couple minutes to check and you never know.

Let us know how it goes.

Did you actually scan for codes or just not check engine light? Most likely filters, and like Dean said just make sure you use genuine OEM filters and don't trust ebay or amazon to get those unless you know what to look for. lots of knock-offs being sold. Highly unlikely injectors are causing your symptoms though.

im runnin the fass fuel pump and that last time i had this issue was when it got cold back in dec \ jan -
even when it first started happenin i was more in clined to thing filters, when i was driving a while bumch i swapped them on a regular basis but since i only drive like 8 miles one way to work and 1 long trip to houston a week, i wonder if some gunk settled up in the bottoms of them

the only reason i called the dealership was it being friday, and seein how bad their diesel tech is backed up. where im at there arent any non dealer diesel techs.
basically i was in a pre planning mode to get repair\rental etc etc etc set up that way i lose as little work time as possible

Got to be honest, I don't know why people swap out their fuel pumps. I've seen more issues with the afterarket ones by far over the stock. Yet people say it's a "must have" upgrade. I could see if you were building a race truck but not for mildly tuned daily drivers. That kind of adds another possible problem area for you to look at now.

If you had a bad injector, There should be codes indicating a mis-fire or something along those lines in the affected cylinder. That's my thought.

basically i was told that it was designed to help de aertate (sp) increase the fuel pressure and cause less cavitation in the fuel injector
