What could be going on here?

Truck drove great all day. Parked it for the night. Woke up the next day still driving fine. I came to a stop infront of my house on a hill waiting for my dad and the truck began to stall and eventually shut off. I fired it right back up no problems and began to drive it. I started noticing that it started to bogg out and would stall anytime i took my foot off the gas. I had my uncle who is a mechanic take a look at it and brought the truck to 2000 rpms and it would run at that for several seconds and then start to bogg down and then return to 2000 RPMS. Drove it to his shop and everythime i let my foot off the gas it wanted to stall and on a couple occasions it shut off complelty, but fired right back up.

Fuel regulator maby.

First thing I would do is check the intake hose connections and possible cracks in the hose after the MAF. Leakage there will upset air volume readings sent to the computer.

tuneup
plugs, wires, fuel filter? if it hasn't been done in a while

Sounds like a fuel starvation problem... replace the fuel filter first, the check the regulator, and if that doesn't fix things then the fuel pump could be bad.
