my truck will quit running when you let off the gas and when you first start it up but it will start back up i replaced the air idle control censor on the throttle body and it run fine for maybe 2or 3 hours and started doing the same thing so i changed the fuel filter also i checked the codes but there wasn't any codes showing it keeps getting worse so i got the idle air control censor replaced and put #2 idle censor in it and again it run ok for a few hour's but started dyeing out again anyone has any help i sure would be thankful thanks Seven

seven; The first thing that comes to mind, would be the CTS. (coolant temp sensor). This tells the computer engine temp., and delivers fuel accordingly. Generally, when a GM CTS takes a dump, it will tell the computer that it is -41F. That's okay, if you are living in Fairbanks, in January. Otherwise, it causes an over-fueling condition. Rough running, dying, ect. With a scanner connected, you will be able to see what the computer is 'seeing'. IAC (idle air control) motors can, 90% of the time, be cleaned rather than replaced, btw.
