Re: 99 blazer stalling problem
Welcome to the forum.
How is the temp when this happens - normal? If coolant level dropping at all then intake could be leaking internal as it heats up. There is a temp sensor in the air intake (small one) and that tells the computer temp to set mixture along with other sensors - but a code should be turning the SES light on - any codes? Clean the MAF sensor (big one in 2" block) in air intake with spray cleaner. Thats a few easy things.
