My 96 850 T has 245000 miles.  When cold it starts fine however if driven a
short distance 1/4 - 1/2 mile and shut off it sometimes wont start.  When
the ignition is turned to start it only makes a faint clicking sound, the
starter doesn't spin.  After 10 or 15 minutes it again starts fine.  If
driven more than a few miles after a cold start everything works fine.  My
initial feeling is that the starter brushes are worn and sticking.  Any help
in diagnosing this odd problem will be appreciated.
Thanks
John
