Temporary Power Steering Failure?

Temporary Power Steering Failure?
I've owned my 1996 XJS for about 8 months and 5,000 miles.
On three isolated occasions I experienced a total power
steering failure when pulling into a parking spot.
As I accelerate and turn the wheel all the way to make a
90 degree turn, somewhere midway the turning of the
steering wheel, I lose power steering. I usually flip the
tranny into reverse and turn the wheel the other way,
backup a bit and then complete the maneuver. As soon as I
turn the wheel the other way, power steering is restored.
Power steering fluid is not low.
No visible evidence of leaks.
I can't recall if it has always happened when turning the
wheel in the same direction.
What do you think is going on.

The last of the V12s used the old Saginaw pump, yes. The 4.0 six cylinder cars used a shaft driven pump....but even those had a similar-looking control valve arrangement.
I've never delved into the later type....never had reason to....yet. However, a sticking valve does sound plausible. Perhaps a teardown for cleaning and inspection would reveal something?
Or, as mentioned, a complete fluid change might be enough to unstick things? That's an easier first step.
