it was driving fine yesterday and lost power on the highway. the wife pulled over, shut it off... long talk...then it started up fine and got her home. i went to take a look and it turns over but won't catch. i don't have a shop or a garage, doing it all in the driveway. where do i start? fuel delivery? EGR? the maf sensor wouldn't stop it from starting would it?

 

First of all we need way more info about your vehicle to lead you in the right direction for help, I would start by checking the fuel pressure, have a read thru this https://blazerforum.com/forum/tech-articles-diy-29/96-fuel-system-diagnosis-23038/
