There's a posibility that the various switches, esp. the kickstand switch test fine while the bike is stationary, but fail at certain circumstances, for instance due to bumps and a weak stand spring or due to resonance at certain rpms. It might be a good idea to try and isolate the switch entirely, by temporarily disconnecting it and jumping the wires manually. Just don't hack up the wiring in the process, be extra careful while riding and don't leave it like that permanently, if it works.
