HELP!!! Car just died WTF could cause this??

check the large wire connector on the passenger side of the engine compartment, back twords the windshield, its black, round and big. Also, hit the starter with a hammer a few times, and double check if you are even getting power down to the solinoid.

it's a bad ground somewhere. Check your battery cables to make sure there isn't too much crud on them at the terminal and make sure they aren't broken. It can appear to be making contact but the if the patch isn't big enough to handle the amps, you get zilch... also check the grounds on your block especially if you just pulled your motor out or did some major work, could have forgotten to attach and or tighten something down. Good luck.

On the front of the block near the oil pan there will be a heavy gauge wire with a hole in a copper crimp for the screw. I believe the wire runs to your chassis but I don't remember. You will prolly have to be under the car to see it. It most likely has a bunch of oil and gunk on it. I think the problem is your battery connections though. The little bolt that pulls the connector tight could have broken causing a bad connection, your terminals could be corroded (use coke and a toothbrush if all else fails). Your copper connector could have a crack in it, thats what happend to me. 5 bucks gets you a new one from autozone. It's most likely something simple. Start at the battery and I think you'll find it. Is it an intermittent problem (does it come and go without warning)? How long did you attemp to charge the battery before starting the car? If a battery is completely dead you usually can't turn the engine over before letting it charge for a few minutes... let me know if this helps...

I take it back, I don't think the ground on your block would cause this problem... just check your battery connections...

I think most of the auto shops (autozone, pep boys etc.) test batteries for free... might want to make sure it's a good battery...
