Starts fine, then dies while idling

Truck started doing this a few weeks ago. It happens occasionally. I start the truck, let it idle for a few seconds, put it in gear and while coasting, (no pressure on the pedal) the truck will sputter and die. Sometimes it fires right back up and is fine, other times it takes a little throttle work to get it started. What do you guys think it is? It happens in the morning after the truck has set for awhile. I would say it occurs about 1 out of 4 mornings that it is started. Fuel filter has about 6k miles on it.

If the idle adjustment does not work......
I am thinking that both of you may have a air leak. You have enough fuel in the IP and lines to start, but then a air bubble comes through and kills everything. You hit the starter which pushes the bubble through and off you go. Just for grins if you have a hill and can park it overnight on it, try it, nose down one night, nose up the other. Any difference? Another test is when it quits, don't use the starter, but use the primer button on the LP. Do you feel that it is pumping air or fuel?
