It could be a number of things, if the battery is good (full charge), you can start the car without an alternator, and will run until the battery discharges. Symptoms sound like fuel pump, but could be any number of other things too, including crank sensor, typical failure when hot. A VCDS scan would be a good place to start, all guess work without that.
