I had the same exact problem with my 2000 3/4 ton Silverado. Since I had already replace the fuel filter and the fuel pressure regulator (gas in the vacuum tube due to torn diphram) I looked elsewhere. I found that the Positive battery cable was caked with the dreaded BLUE corrosion. Pull the cable off of the battery, twist and pull the bolt out of the cable end (with red shield) and then pull the booty/shield off the the cable end. I had tons of corrosion on the braided cable and contact plate causing insufficient power to the engine. I cleaned all of the corrosion off of the cable and adjacent parts and it cured the "Dieing at Idle" problem for me. Good luck.
