My 2003 Blazer stalls while driving. This does not happen on cooler days, only when it is hot out. It does this primarily during city driving although it also has occured while highway driving.

Have seen the same problem on more than one. The cause was a bad fuel pressure regulator. You need to test the pressure output and see if it is holding residual pressure as it should. Also test the pressure and see if it is within the proper range.
