Next time it dies, try opening the gas cap and see if it sucks air in. If you have the wrong type of gas cap on the filler, it will create a vacuum that is difficult for the fuel pump to overcome. I've had this happen on motorcycles with gravity feed, worth a try. I also had an electric fuel pump suck rust into the inlet screen and kill the engine at highway speeds. Waiting a few minutes allowed the rust to settle and the car restarted. Ended up replacing the tank and putting in an inline filter. Good luck!
