This simple problem has become more complicated that launching a Saturn rocket.
Is it an actual loss of oil pressure or is it an oil alarm problem ? ? ? ? Water pumps don't affect oil pressure. Oil drips don't affect oil pressure.
In terms of money and effort, RPM is your first check. If that's not the problem, a new pressure sensor (switch) would be the next logical choice AFTER insuring that you do not have an intermittant ground in your alarm system.
Either start with the most basic approaches previously suggested or just ignore the alarm and see if your engine seizes up. Then you've got proof it was an actual pressure problem.
This COVID-19 isolation is really taking a toll .

@garymalmgren posted the best solution but unfortunately fitting a pressure gauge on to your oil system can be a bugger if the threads are not compatible with an NPT gauge. Re-threading, avoiding getting cuttings into the oil system as the next stop is the bearings. Problematic.You don't know what the oil pressure is.
You need to know what the oil pressure is before you go to any next step.
An oil pressure gauge will tell you much more than I or anyone else on here can.
