Update to my earlier review:
The issue turned out to be a faulty fuel pump and pressure regulator. The dealer removed and replaced both.
I have to say that both the dealer and VW corporate handled this very well. The "zone administrator" was significantly less helpful - so be aware. VW Corporate extended the terms of the warranty on my vehicle (full factory not aftermarket warranty, by my VIN) to 4yrs 48K miles. VW does stand behind their product! Since then over 8K trouble free miles in ~10 weeks. Very happy, happy, happy now!
