Usually when you have symptoms like this, we would check the fuel pressure. If i were taking a guess, I would say that you are going to need a new fuel pump (which is easy to do btw) and two new injectors. If it's gotten this bad, i would expect that you might be in some trouble though and might be going back a couple of times, because once you run on low fuel pressure for long enough, the injectors will slowly start dropping one by one over time. If it were oil pressure, the injectors that would have problems would be side by side in the bank, but because there is an injectors between 4 and 8 (#6) i would assume it wasn't an oil problem. I can't say for sure without the truck in front of me, but my best educated guess.
And just a peice of advice. Don't drive it unless you have to. You are asking for a problem if it's the pump and could very easily leave you stranded on the side of the road, not to mention, are asking to ruin the rest of your injectors if they aren't bad already.
I hope that helps, and sorry to be the bearer of bad news....
