Could be the alternator, not charging the battery correctly.

Get a meter out and test the voltage from the alternator to the + on battery.

Should read around 12V +

Sounds like the immobiliser key isn't being picked up by the ECU.

Does it run for about 2-3 seconds then just die? If so I suspect that the ECU and the Key aren't talking to each other. Have you tried your spare key?

If you can, (with a window OPEN) try pressing the locking button on the key during the brief seconds the engine is running, sometimes this will resync them. If not probably off to VW or a VAGCOM equipped man.
