It sounds like the catalytic converter could possibly be almost completely plugged up not allowing the exhaust to leave the engine like it should. It just builds up in the cylinder head and when it gets too much in it built up and there's no where to go, it'll stall the engine. By letting it sit for a few minutes, it gives the exhaust time to find a way out and the car will restart.

Sounds like the torque converter clutch solenoid is bad. Unplug it and see if the problem stops. Unplug the 4 wire plug on the front of the transmission.

Fuel filter. Timing/timing chain. Idle air control valve. Idle sensor. Vacuum leak. Probably one of the above, but the filter is cheapest place to start. Change your air filter too, if you haven't for a while.
Testimonial: "Great thanks so much! This will be a place to start, more than chevy dealerships have given me! Appreciate your time :) Thanks again!"

a bad crank sensor can cause this. shuts off while going down road, and will start about 10 min, later with no problems runs fine until it quits again. hope this helps,
