My blazer was on for like 10 minutes idling and it just stopped died out .tried to turn back on but it wouldnt start up no more
Make sure battery has a full charge and connections all good. If it cranks good but won't start, have a helper crank it while you visually check for spark at the plugs. If spark everywhere, use a gage and check proper fuel pressure, check fuel injector pulse? Check applicable trouble codes? Those are the basic checks, in my opinion. Let us know what your missing, if anything?
