2000 7.3L surging while warming up

Does anyone know why my 2000 F-250's 7.3L has been surging the last couple times I drove it? It did it last night & I thought maybe I was pulsing my foot on the accelearator or something, but then it did it again this a.m.

What is happening is after I drive it for a mile or two when I press the accelearator, the truck seems like it's not taking fuel or misfiring and kind of surges, bucks, or starts sputtering around 1,500 rpms. The crazy thing is this totally goes away after the truck warms up. So it doesn't do it when it's cold or hot, just briefly after it's run for a bit, and before it reaches operating temperature.

The SES light hasn't come on either. I also don't know if this has anything to do with it, but here in Southern OH it's gone from being in the single digits to the 50's and 60's over the last few days.

Anyone with any ideas please let me know. I'm worried this is going to get worse & leave me stranded somewhere.

Man I have the same exact problem with my truck. I live in New Orlean and we go through a few weather changes of a 30-40 degree change in a day or two. When the truck warms up it runs great but if the guage is below the cold line it will run rough and die and I will have to restart it and let it warm for 30mins. If I start it in morning and sit in the truck to try to keep pushing fuel through the engine(rev it up) the RPM's will just barely go above 1000. I could floor it and it has no power. But again like I said when it has warmed up it is running great. No check engine lights on or anything. ANy goes?
