Stop driving it and check the oil pressure with a mechanical gauge sounds like an oil pump failure overpressurizing or the oil filter is loose.

When the engine is running and the pump is working hard to push oil through the system, some means of controlling pressure must be used to prevent too much pressure from building up in the lines and filter. A spring-loaded "pressure relief valve" in the oil pump (or next to the pump) opens when pressure exceeds a certain limit (typically 50 to 60 psi) and either reroutes oil back into the pump's inlet or the oil pan. This prevents a dangerous buildup of pressure that could rupture the oil filter or blow out press-fit oil plugs.
