It's very rare for a main relay to cause a stalling problem.

well if all that checks out (the car will drive fine with the battery totally dead, I know I got my beater 4 door home in a long trip and the battery was ****. Turn it off and you wouldn't even get a dome light) check the ground on your thermostat housing and the alt fuse under the dash.

Alternator fuse under the dash, main relay, or main power fuse under the hood

The battery probably ran down on volts. The alternator might not be charging the battery. You might wanna check your charging system.

jump it and if you can get it to run unplug the terminal on the battery and see if the battery light turns on, if so your altenator is shot
