How's everyone doing. Well here is my story:

I got over $3000 of work done on my 2000 chevy blazer last year. I had the mechanic check everything from the battery, interior lights to exterior lights. All of this work was completed September of 2008. This year (I'd say it was March/April), i was driving back to Brooklyn, NY, and the truck died on me in NJ. I waited about 20 mins, started back up and it was good to go. Got to NYC, and the mechanic informed me that the alternator was bad. Got it replaced. Came back to Maryland, and everything was fine. May timeframe came around, and one day the truck died on me again. The temperature was around 90-92 degrees that day. Thought it was the alternator, had it checked it worked fine. I currently live in Maryland and we really havent had temperatures over 90 (luckily) alot this season. But since the incident in may (when it has been 90+ degrees outside), the truck decided to die on me. Last Friday, it was muggy (98 degrees outside) and it died on me. I waited, waited and finally i decided to have a tow truck take me to a mechanic. When i got to the mechanic, it started it like nothing was wrong.

So to make a long story short. My opinion i think the truck is possessed when its 90+ degrees outside. I lose power and end up on the side of the road...like i just ran out of gas.

Any help would be appreciated.

I am still searching for that same problem on my 98 blazer,I have put 3 fuel pumps on my truck in the last year,only during hot weather it will act up,it will run fine all winter,went to the chevy dealer today and my truck was not throwing any codes have you checked your truck for any codes?

 

Your problem is most likely the ICM is bad..

 

I agree Ignition Control Module, Crank sensor or coil But the ICM and Crank sensor will Make the truck stall out and after it cools down will restart Start there.

 

Thanks for the quick responses. Im headed out of town today, so as soon as i get back, i will try that out. How much do the ICM's usually run?

 

Napa in my area of CT sells two different ones anywhere from $80-$145 Check Rockauto.com they have pretty good prices and quick delivery

Keep us posted and good luck !!
