2002 blazer
160,000 miles
p0410 and p0128 codes

Blazer runs okay in morning drive to work. Afternoon drive home stalls after driving 20 miles. After short rest, I can pump gas and get Blazer to start enough putput off to a parking lot. After long rest, Blazer will start and run normal. weather is hot but vehicle temps are okay.

After reading all these threads, I'm just trying to figure out where to start. Can't duplicate problem while at home. read that po410 will not effect driving conditions, so I've narrowed it down to ICM getting hot or Fuel Pump overheating.

Please Help!

 

I would try a new cap and rotor. Get AC/ Delco parts. You are having a spark issue and the cap and rotors on these newer blazers are known to go out quick

 

I just replaced my cap rotor wires an plugs. The cap came with a tech note to remove one of the bottom screws under the rotor to allow heat to escape. I did not save the paper but it was a AC delco cap. Hope this helps
