Audi 5000TQ cutting out ...

["Joseph Vella" <joevella@user.rose.com>]

 I have a strange problem with my 5000TQ and I hope you can help.
After about 20 minutes of driving, the engine will lose power, such that
you cannot continue to drive, and will quickly stop running altogether.  
It will  restart  immediately without trouble, and you can, in fact continue to drive 
if you simply  flick the key quickly off and on.  This situation will repeat in increasing
frequency  as you continue to drive.
  
 At the time this happens, the fuel pump will make a much louder noise than 
usual, so I shorted the fuel pump relay as a trial, and the same situation
occured. Although the fuel pump was continuously running, due to shorting 
the relay, cycling the key quickly as I drove, allowed me to continue to drive, 
just as before.  What would you suspect here ??  THanks.
