What is the fuel level in the tank?
Is it stalling when you let off the pedal at 1500 RPM?

It is 3f right now guess I didn't think about gelling. It has been in the teens to low 20,s last few days. The truck was idleing when it stalled. Fuel tank is full,that is the first thing I thought. Been there done that.

I wonder why there have been so many fuel probs? Most suppliers KNOW it gets cold in the winter. Seems like their dropping the ball with the winter fuel supply?

One of our diesels had fuel gelling and it was a lot warmer than 3F. shot the fuel filter with a heat gun for a few seconds and it was good to go.

I was reading the other night when a gelled fuel issue came up.
ULSD has a third classification WDO or wax drop out in addition to CP and CFPP.
Looks like WDO may be a bigger issue than CP and CFPP with ULSD.
Here is the article.

well back to square one truck died on son last night. I took it for a 10 mile drive, (after new filter and lift pump)Ran super good son took it to plow his driveway stalled couple times,then on the way back to my house it died and would not start. So going to put diesel kleen in it. If that doesn't help I am going to put new fuel line from tank to lift pump.

Yes there are specific directions for installing the straight arm lift pump, they must be followed to the letter or lift pump and/or engine damage may result.
If gelling is the issue, the fuel may not be getting to the lift pump.
Chuncks of wax can and will stop up the fuel lines, filters and strainers.
Possibly you had the shop warm enough to dissolve the wax, when you pulled it back outside the fuel gelled and stopped the lines up again.
I watch the Weather Channel a lot, if you are in that brutal cold air mass, I think gelling is your issue.
