It's because the pumps are all aluminum and they wear very fast when
cold. Once they reach operating temperature, they wear very slow.
Also, the pump has one piston in the center & a distribution plate they
aligns with each output port in turn. This means that the one little
piston is working 8X harder than the inline pumps used on Mercedes
diesels.

Why is that? Just curious, I've been thinking it'd be cool to put a 350
diesel into an S truck but that would probably see quite a few highway
miles.
Is it because of lower speed running or stopping and starting?

By 81, the Olds diesel was a good engine.
And I understand why your friend kept 2 pumps around. The engine uses a
rotary pump. The pump will go 100,000's of miles on the highway but
50,000
city miles will wear out.
I owned a 81 Pontiac Bonneville with the Olds diesel. It was one of the
best
cars I've owned to date. I killed the engine at 150,000 miles.
Thanks,
