Why does my 1994 Chevy Caprice stall while driving?

I have a 1994 4.3liter V8 Chevy Caprice. Sometime the car will start and drive fine with no problems. But most of the time after I have been driving it for 20 mins or so the car will just shut off. The electrical system still works fine so I know its not the battery or alternator. After it dies it takes me about 10 mins to start it again. And then other times before I have even driven it and I come out to start the car it won't start. So far I've had the ignition module, distributor cap, rotor, wires and spark plugs replace. Any ideas?

sounds like you have a sticking choke, check the carburator an fuel system . make sure your fuel lines aren,t too close to the exhaust, could be vaporizing fuel, called vaporlock. good luck
Do you know if your Auxilliary Battery Post has ever been changed? I had the same symptoms in my 94 SS. There was a TSB out for this problem. At RMS they have a PDF of the TSB along with all the parts to fix it. http://www.rmsautoparts.com/proddetail.php?prod=12176639
