2004 Chevy Aveo stalls while driving, but will restart a few minutes later

Worked on it a bit today. Started it up. Started unplugging stuff trying to get it to stall. It's amazing what it will run with disconnected. I got to the crank sensor. Disconnected it. Obviously it stalled instantly. Exactly like it did when driving. I tried pulling the code. It did not throw a code. Same as when it stalled on the road. I will drive it to work tomorrow with my scanner attached. Hopefully it stalls and I can record what the readings were at the second it went down. For now I'm leaning toward a malfunctioning crank sensor. Just has the symptoms that I have seen in other vehicles with that going bad.

It's not necessarily an electrical problem. Has the fuel filter ever been changed?

Failing fuel pump? Bad coil? If it's a bad ignition module usually the car won't re-start or run.

The first step is to determine whether it is electrical or fuel related. Easier said than done...

I am having difficulty determining fuel or electrical. Like you said. Easier said than done. Especially since the occurrence is random. I have never changed the fuel filter. Could be an easy and cheap try. I'll pick one up tomorrow.

I was thinking electrical just because of how it stalls. It doesn't stutter or stumble. It just turns off. Just like you turn the key off. It would be easier if it just quit and would not restart.

&)&^#* ME!!! A fuel pump is over 300$ for this car!
