Dumpweed

I've tried doing a search for TSB's, but didnt see much. My car is an 06 manual GT. Well, we were out of car soap, so i decide to go get some in town. well on the way back from autozone, its 4 lanes, i go to pass a car, i'm in 4th, it just dog's down...so i down shift to 3rd, and same thing...so i pull onto some housing edition. it just shuts off, i turn it back on to pull it off to the side, as i'm right in the damn middle of the road, and it goes to about 300 rpms and just dies again...i take the keys out and someone helped me push it off to the side out of the way...its on the tow truck to Ft Wayne to the dealer, anyone know what TSB if any?
