So a few months ago (after the x-charger install) I was having problems with my car shutting off while driving. I replaced the battery and alternator. Yesterday I was driving and the car started losing power like it was out of gas (had a half tank). Got the check engine light and my wideband read lean like 20-22. So I waited a minute, restarted, it read rich 10-12. Ten seconds later the car was fine. Now today the car shut off in a drive thru and took a few minutes to start. I don't know if it's a fuel problem (fuel pump) or an electrical problem.

Sounds like the fuel pump to me....

Nick, check the ground wires on the passenger side to the left of the radiator cover. The one on the left in this picture was loose on mine and the car was doing the exact same thing.

Did you have it custom tuned... Might be a problem with it

Two things mustangs of new and old are famous for aside from major awesome-sauce:
Rust and electrical issues.

Both issues have held for every generation.

The car has an e-mail tune from Doug that tons of people are running, and everything read fine when it was on the dyno.

I checked the ground wires and they were fine, but I'm sure there's some electrical issue going on somewhere.

Nick, that car just isn't giving you a break is it...
