A lot of good suggestions .It very well could be charging system or battery .without seeing or being able to test it is hard to say. Your bike being a 99 it doesn't have the sensors that are on A 07 so I would rule that out. One more suggestion your engine light will come on if oil pressure drops below 3psi. could be as simple as the wire on the sending unit having A bad connection. Although I would suspect the same as others.
