Been riding Hondas since 1967. Last year on a trip far from home, stopped for a break, bike did what you describe (except for the neutral light). After 2 hours of disassembly, frantic phone calls etc., noticed the kill button was on. Now that's the first thing I check.
I'm not sure where your neutral switch is but if you can pull the wire and ground it, that'll tell you if the switch is bad.
Another time the symptoms were exactly as you described, again far from home. Push started it. The problem was in the reverse setup. Don't remember the exact cause but I adjusted the cables, checked the switches....OK now.
Good luck. Tell us the outcome eh?
