Sluggish steering?

[Avinash Chopde <avinash@acm.org>]

Looking for a diagnosis from the "Net-Car-Doctors" :-)

So, my car (1990, 100) has suddenly developed steering problems.
At parking lot speeds, it seems as if there is a loss of power
steering -- steering is very hard, don't know if it is just a
loss of power steering, or whether there is something wrong that
is actively resisting the steer...just happens for a second or two,
and then everything works ok, but all this does get repeated 2-3 times
a day...

Any ideas as what could be wrong?
And if you have undergone repairs for this for your car, how much
did it end up costing?

Thanks!
