Two minutes can be a really long time to go with no oil pressure. For the light to be flickering, especially randomly, it is likely you have nothing more than a defective pressure sending unit, but the only way to know for sure is to have the actual pressure checked with a mechanical gauge. If it is indeed low, damage to the engine bearings will occur very quickly. That will turn into a very expensive repair.
