I had a 1995 honda F3 and I had that problem, it was because I hadn't turned the fuel on, it happened a second time, this time I had the fuel on but it ran out and I had to turn it to reserve. Happened a third time, this time I had the fuel on and it wasn't out of gas, I didn't know anything about bikes so going on a friend's recommendation changed the spark plugs and it started up first try.
