Hesitation problem

I just had a hesittion at start up and it continued while driving. I immediately thought coils or plugs. Since it seemed electrical I decided to do my old standby and disconnect the ground under the drivers floor mat. I started the car up... no hesitation. I don't get this vehickle. I had a dash info center go crazy on me a couple of months ago and disconnecting the ground cured that problem as well. I can't believe the electrical gremlins in this truck. I will have to create an after market switch to disconnect the battery every time I have a problem!!! (just kidding) Most sane people would have divorced their truck by now but I'm willing to work through our problems. I don't know why I keep coming back for more but I still love the Cayenne.

P.S. I just replaced the battery 2 months ago so I know that is not the issue.

Any thoughts?

It could be one of the fuel pumps starting to fail. The '03/04's had a few electrical problems but they seem fine after that.

You might be correct. I had it happen again but noticed the fuel pupm start up sound right before the hesitation. Do you know if it an easy fix? Is the pump external or in a place I can easly swap it out or is it in the tank?
