First , have the oil pressure sending unit replaced, if the problem continues after that is done, I would start focusing on the oil pump.

You may need a pump or your bearings in the engine may just be worn out.....or it could just be low/dirty oil.
That light is a warning. If it ever starts flickering or stays on while driving shut it down quickly. The first sign of an engine about to go is the light staying on longer then it ever has.
I have been working on nissans for 15 years and have never come across a bad pump even on cars with 300,000 miles. It is more then likely internal wear. Get an oil change now it may save the car. Look for any shiny metal flakes in the oil. This will be bearing meterial.
