A Bad Day

I'm considering removing the oil pan first, to see if the intake tube fell off, or as you suggest, got plugged somehow... Can't think of anything else to try.

No horrible noise, so that's good. I guess I'll start by removing the front drive shaft and the oil pan to check the pickup tube, but I'm not terribly optimistic. Seems like the next steps will involve removing the whole front end of the tractor, so the drive shaft would be the least of my worries.

Id start with the oil pressure switch.unless that’s what you’re calling the sending unit.

The problem lies with the pump or related to the pump.
Check all plumbing related to the pump if the tubing is
clear and the pickup tubing is not disconnected from the
pump then its the pump that needs replacing.

Chevy had a re-occurring problem where the o-ring seal between the pickup strainer and the pump failed. I have that issue right now. For some reason, your pump is either not picking up oil, or not able to produce the pressure required. Without knowledge of your unit, my gut tells me to pull the pan and inspect, starting at the pickup tube and going up from there without any other symptoms presenting themselves, such as oil in the coolant, knocking, squealing, etc.
