Still playing around with this issue.  I had a Chicago independent shop
install a salvage pump back in January.  Well there was a minor connection
leak.  I live in CT and am back in Chicago this week.  Well they said they
fixed the leak (only just picked up the car today, so ...?!?), but there is
a "new" issue.  When I first start the car, the PS assist (level) is EXACTLY
as before (GOOD), but after a minute or two, the assist level is stiffer
than it used to be.  This condition is repeated every time after the car is
stopped (off) and restarted at a later time.  The PS is definitely working
... just stiffer.  Any insight?

Thanks as always.
