5-10 psi at idle with a warm to hot engine is not unusual with a well used engine but is low enough to ring alarm bells if that is the reading at speed. The manufacturer will issue specifications for an oil pressure test but as a general rule the test would be made at around 2000 rpm and the oil pressure should be around the oil pressure relief valve lift-off pressure which commonly is about 40-45 psi but could be higher or slightly lower.

Oil pressure has little relationship with engine power as long as it still has some...

If the oil pressure is low the cause might be simple or it might be complex and expensive, but whichever it turns out to be, rectification should not be delayed even for a day...

Sounds like a bad pressure sending unit, or a partially plugged passage going to it. First though, check that the wire connection is good on the unit. Sometimes just adding a good additive such as marvel oil will free it up sufficiently to restore function. With no noises etc, that's the most likely source of your problem. If not, driving as you have been the engine would be junk by now!!!
Good luck
