Engine Oil light

I have a 2001 325 and my engine oil level light kept on coming on for 20 seconds and then goes off. Now the Check Engine Soon light comes on sporatically and the past three days my car has stalled once and has had a delayed start. Once my battery light and my Engine Oil pressure light came on at the same time. I shut off the engine and started again and all lights are gone. But that is when the car stalled. I started the engine again and no lights and the car worked fine. I am taking it in five days to get it checked out but not sure if this is serious that I should take it in ASAP. I just changed my oil two months ago. HELP PLEASE!!!
