96 blazer was running fine all the sudden died wouldn't start found low on oil filled truck started but when push gas to hard losses all power till u let off gas then you canease back into the gas

SOURCE: starting fine, driving fine, but dies while going down the road

Next time disconnect the negative and not the positive if it ever happens again. This happened due to the PCM needing to be reset.

If this engine is a VORTEC then you may have a problem with the internal fuel system. Under the top plenum there is a fuel reg and poppet valves that inject fuel into the cylinders. Sometimes the tubes that run fuel from the reg to the valves can leak and cause your problem. This cannot be found with pressure check because this occurrs after the reg. PS fuel mileage will go down. Let me know if this helps.Moe

SOURCE: 1990 full size blazer starts fine idles then dies

sounds real easy either a bad idle air control solenoid or more likley a blown throttle body gasket. to test fro a blown gasket, with engine running and cool spray carb cleaner or brake cleaner around base of tb were it bolts to intake. when it hits the bad area, should idle down and be normal for a second or 2. iac is possible,try this first since its so common and let me know

SOURCE: Runs fine till warms up then losses power and dies

My 05 silverado 5.3v8 was stalling dead when it reach a temp of 170-200 degrees and wont start until cold and do the same thing till warm. I changed fuel pump, crank sensor, bought a cam sensor also.  It turned out to be a disconnected single ground wire that runs under the power steering and connects to main ground on bottom front. Now engine runs fine. I changed power steering a couple of times and must have wore it loose.
