Hi. The most likely cause of this problem is the oil level sensor has an intermittent problem and is about to fail. There is electrical circuitry inside the oil level sensor that sends info to PCM. Sometimes this electrical circuitry gets shorts in it and causes an intermittent problem like the one you are experiencing.

I suggest you have a certified technician, such as one from YourMechanic, come and replace your oil level switch to get your car back in full working order.
