I have a 2000 blazer. seems like when it gets too warm, it sputters, loses compression, then stalls. We've changed the fuel pump, the ignition module and have cleaned the egr valve. Anyone have any ideas?

 

yes maybe a problem occuring, had the stalling problem when the vehicle would run hot, look at your intake and your gasket's, i blew a head gasket and right before that it ran just like yours did. unfortunatley im in the process of replacing my motor but, make sure you look that thing over good but, also a note mine had like 287,000 miles on it

 

cat converter ? check fluids ? uhh thats all i think for now
