Was it an actual mechanical failure? Or was it the vibration of the bump strip doing something nasty to the pump reservoir so it sucked air in to the power steering lines?

That's also a possibility.
I once owned a Saab 900 Turbo 16 S which developed an issue where as it warmed up it would lose the idle RPMs. This meant you would be driving along in gear and need to slow or stop so you press the clutch in and the engine dies with immediate loss of power steering and only a couple of brake applications before you lost power brakes as well. Had a few interesting moments with that! Of course it only did it when starting from cold as it warmed up and once it did it, you just restarted it and it would idle fine. Never got to the root cause before I moved countries and sold it. That was bad enough, can't imagine what a big rig like yours is like when it loses the power assist.
