Check for any stored codes. If it happens after the engine has been heat soaked it could be an ignition pickup issue. Check for spark with a spare plug. Once the engine cuts out, pull a plug wire, install the spare plug and crank the engine while checking for spark. No blue/white spark then you know it is ignition. If strong spark, reinstall spark plug wire and remove the gas cap. Reinstall and see if the car starts. If it does then you know it is probably a EVAP issue causing a pressure issue in the tank.
