Loss of power

I have a 1999 F350 super duty diesel. Just recently my truck has been losing power. I will start in morning seems to drive fine up to about 1900 rpms then all of a sudden the rpm's will drop I will then press gas pedal to the floor and the rpm's will continue to drop until the truck is stopped but engine is still running. Then after a few minutes I will press the accelerator and sometimes the truck will run fine other times it will pick up a little speed then rpms drop again or sometimes rpms will drop but then rpms rev back up and the truck drives fine. After this truck drives fine rest of day. Todat the truck stopped I parked for awhile with truck running then all of a sudden the rpms increased and the truck drove fine. Any ideas what is going on. Thanks

Fuel filter or pick up tube in your tank. That's where I would start anyhow.
