When was the last time the fuel filter was changed? When you do start the car is there a whining noise from the rear?

Changing the fuel filter is something you can do yourself. Its located under the passenger side rear door. Make sure you get the right one (3 pipe or 4 pipe) before changing it. If you are hearing a whining noise from the rear it could be your fuel pump.

Fuel filter is not expensive.

I have the exact issue on my '98 2.8 A4. It is difficult to start or stalls after filling up with gas, posted about it in the B5 section.
