2000 Mitsubishi Galant Dying at Random

Does the battery die after it runs for 7min? is that the only code you are getting?

There are numerous reasons for a vehicle to stall at random. Is the check engine light on? If so, scanning for codes would be a good place to start. Having a fuel pump pressure test performed will let you know if there is actually a fuel pump/power supply issue causing the stalling

You have a real auto repair shop ( not auto parts store) look at stored codes, & any freeze frame data
Do not clear the dash light or you loose data & ability
to diagnose & resolve the issue

Alternator replace >check voltage at battery when running needs to above 13.5 volts

adjust idle

I have this same problem! EXACTLY. Did you ever find the problem??? Mine is 2000 Beetle.

My car does this when I use my key that the computer chip AKA (VATS) is messed up it will start then immediatly die. The car will start without a working vats key then immediatley die.

The chip is inside they key and isn't visible

all the sudden the check engine light came on and it started to idle funny and dying at stops. I had a diagnostic done on it and changed out the idle air control valve but it doent seem any different. and the check engine light is still throwing the same code. we adjusted the idle up so i could drive it with out it dying but it is still acting funny.

this can be caused by a bad fuel filter or dirty injectors. try a bottle of fuel injector or fuel system cleaner in a tank of gas. i suggest lucas products which can be found at any parts store.
