My 95 blazer will stall while driving for a long distance on a very hot day with A/C running.

A while ago it used to this and if left alone for 15 min or so it would restart, then stall again if driving conditions remained the same. I mention this because when it happens now, it will not restart unless it is left overnite, or longer.

any thoughts???

 

Is the check engine light on?
When was a tune up last done?

 

No check engine light is not on.

Hmmm, tune up, not sure.

BTW, now...if it just sits in the hot sun for too long it will be hard starting.
