Make sure it has oil. Remove the oil pressure sending unit and install a gauge. Make sure you have at least 30 PSI of pressure. Make sure the oil doesn't need changing. If it's too thick, it won't be able to be pumped properly.

If the oil pressure is good, replace the sending unit. The vehicle's computer is probably shutting it down when the low oil pressure is detected to prevent the engine from damage.
