Sounds like youn have a serious vacuum leak. Buy a vacuum tester and find the vacuum spec for your truck. Usually most cars will pull around 20 in Hg at idle. Also you should look at your idle control valve and your throttle position sensor. But sitting at idle and pumping your brakes will tell you a lot. If you do that and it stalls, then you have a real vacuum leak somewhere. Start hunting.
