Anyone have any idea about this one?? Blazer always runs great, wife runs into McD last night, comes out and COMPLETELY dead. She hears clicking, buzzing, etc from under dash, pass side. No lights, no starter clicking...Battery dead as can be.
I go out there this AM and jump it and it immediatly starts fine and easy, take cables off and it looks like battery is charging great. I let it run for almost 40 mins. I get in to drive it home, back out of parking place and start going forward. I travel about 40 feet in parking lot and immediatly EVERYthing cuts of and dies. I coast back in a parking spot. Battery is absolutly dead again, with no lights, starter click or anything. As I said I think alternator is charging fine, I think battery is newer. Something out of the blue seems to be immediatly killing all electrical and causing an immediate battery kill... Help, any thoughts?? Thanks!

What is battery voltage not and running?
I would check battery cables and battery ends and grounds real good.
Post back your battery voltage at cable ends and to fuse box.
