Ur-q starting (not)

["Jim Haseltine" <Jim@ur-q.freeserve.co.uk>]

On occasion my 88 Ur quattro will refuse to start, usually at the most
inconvenient times and places. Tends to be when trying to restart after a
journey, the starter just appears to be completely dead, just 'clunks' but
doesn't turn. It did it tonight in my drive after my trip home from work (25
miles fairly fast so things were hot under the bonnet) and the only response
to the key was a click from the starter solenoid. It started fine later. The
starter is about 18 months old.
Theories?
Starter suffering heat soak?
Some sort of ignition switch fault?
