Probably you have a bad connection in the starter. The initial try at starting arcs the bad connection & then there is no connection. Best start at the battery with plenty of boiling water to clean the terminal & clamp. Then both ends of the earth strap. Next the big terminal on the starter. If that all doesnt fix it, time to remove the starter & clean it out.
