I'm with WREKS start with cleaning cables on back of starter. You did not say what of battery switch/ single battery/duel batts. While you are cleaning cables on back of starter just for fun clean all contacts on Battery switch and visually check all cable runs down to starter looking for wear damage ect........ After that I would I lean towards solenoid/starter testing.

A 1999 engine is getting a little long in the tooth I would suspect a worn out/corroded starter.
