I have experienced this problem on similar vehicles. You should try and replace the coolant temp sensor. If it is not reading the correct temp to the ecm, it will not get the right fuel map. Also, the cts will not always throw a code.

Sounds like the injectors may be bad or just really dirty. You say that the truck is only used as a plow truck, so I would assume that it sits alot. If you dont add any fuel stabilizer to the tank, the fuel will start to degrade and the will gum up your injectors. One thing you can do is to pull the air cleaner assembly off and look at the injectors while the truck is running. Look at the bottom of the injectors while it is running. The injectors shouldbe spraying fuel with a fan spray of fine mist. If you see any drips of fuel in the this fine mist, that injector is at least dirty or on its way out. I would recommend that you change your fuel filter and then get some fresh fuel and the purchase some Seafoam fuel injector cleaner from your local parts store. Dont mess around with anything else. GET SEAFOAM. If it is in a plastic bottle it is not strong enough to do anything. Seafoam is in a metal can. Dump the seafoam in and run the truck as much as you can. This will help clean out the injectors.

Check your EGR valve make sure that is working properly, if it is then go to the fuel pump, just a cheaper fix to go after the EGR then the fuel pump

It is one of 2 things fuel pump or Crank Shaft Position Sensor. Best bet would be the Crank Shaft Sensor, and what that does is tell the computer where the crank is and when to fire the right plug at the right time

Engine stalls or RPM
fluctuates at idle up and down or dies near idle.
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
