2004 Volkswagen Touareg

Engine Performance problem
2004 Volkswagen Touareg 6 cyl All Wheel Drive Automatic 76,000 miles

While filling up the car it vibrated and shut off. Later, while driving the car started to slightly vibrate. Soon the rpms and speed started to decline. Maintaining 4,000 rpms kept the car alive and anything below that it would die again. Once we started it back up again, when flooring the gas, the car barely sped up and thrusted forward every 6-7 seconds from then on. Was able to do about 60, 70 or 80 as long as 4,000 rpms were maintained. Once we drove over a pothole the problem ceased, only to return soon after. What do you think the issue is?

First of all it is a no no to fill up your car while it is running, that will set an automatic engine code, and the computer will think there is a leak in the fuel vapor or return system, and you failed to mention in your description if you have an engine light on. I will need to those things to further assist you.
