Fool pump failing?

[quk@isham-research.demon.co.uk (Phil Payne)]

Climbed into the ur-quattro this evening for a quick jaunt down to
London.  Got 30 miles into the trip, and the car started bucking like
a Texas steer every time I used the loud pedal.  I could _just_ (on a
flat, level motorway) reach 70mph - any attempt to go faster resulted
in me going slower.

The fool pump has been alternately buzzing loudly and silent.  When I
pulled up at some lights on the way home, I could feel the vibrations
on the handbrake handle.

I suspect a strongly dying pump - demise imminent.  I've never had one
fail gradually before - is this how it happens?
