Variable oil pressure

Oil pump pressure relief valve or trash in the pan...... Either way u gotta drop the pan to fix it. Are u sure the gauge is working correctly and is not screwing with your head, obtain a mechanical gauge and double check if in doubt.

The first thing that you should do is change the oil pressure sending unit. GM oil pressure sending units have always been notorious for doing this kind of thing after a while. I've replaced literally

100's of them for this type of complaint. Start here, and if that doesn't fix it, you will have to dig a little deeper. If you don't want to spend money on a sender that may still be ok, then you will need to get a mechanical gauge and check the oil pressure with that. But I'd guess that the unit is faulty.

What things might cause oil pressure to start varying like this, and what can be done to correct it?

I'd agree with the gauge. Usually an oil pump either works or it dont.
