Your oil sensor is detecting a fault condition, or has become faulty itself.
Normal operation is that the rocker switch breaks the wire going to the sending unit so that engine will try to start. But, once started, if fault exists, the sending unit disables ignition.
Depending on model, the sending unit may detect low oil or low oil pressure. Either way, there is a single wire going to the sending unit, typically located near the oil filter (if equipped). Follow the wire, and you will come to a connector inline that you can pull apart. If engine runs now, and you are sure that you have proper oil pressure and level, then sending unit is bad. Don't run engine without making sure you have proper oil though. You can burn it up in short order.
