Tired of the pushbutton....
Unless you luck out and find the one dirty, loose connection, you will always have this problem until you either replace the wiring harness in your bike with all new or add the relay like outlined above. Don't trust the bike's voltage gauge, they are only close, not real accurate. They give you an idea of how much voltage is getting to the gauge through the 16 year old wiring harness. Read through that thread above all the way, it has many useful posts with lots of good information, from adding the relay to cleaning the solenoid and making sure everything else in the starting circuit is up to par. Adding the relay will most likely fix your problem for good, and only costs a few bucks for the relay, connectors and wire. Much cheaper than throwing a starter at the problem only to have it keep occurring!
Didn't you say you already replaced it? If you actually haven't yet, you should. That could be the problem.

You now need to get a true rms volt meter and test your charging system at the battery while she's running over 1500 rpm.
If you don't see > 14 volts no greater than 15.5 you have a problem.
Regulator or alternator problem. 12.5 volts ain't cutting it and if that's all your getting look no further. Youve identified your occasional no crank issue.
If I missed a post I'm sorry but I just couldn't read all of them.
If the load test fails, get a new battery otherwise I'd check the battery terminal voltage with the bike off. A fully charged battery should read 12.6 -12.8 volts dc or slightly higher. Start the bike if you can, and record the voltage with the record function of the multimeter if this feature is available, while starting the bike. The voltage should not drop less than approximately 9.6 volts. Check the voltage with the engine at idle. At idle your voltage should be about 14.5 - 14.7 volts dc. If not, rev the engine to 2000 rpms and recheck. This will let you know if the battery is being charged.
If the battery is not being charged you will need to check the charging system. There are several posts on this forum on how to do this.
If battery is being charged. I'd recheck all connections, fuses, relays etc...
You might want to remove and reseat the starter relay or even replace it just to rule it out. Minimal cost for a starter relay.
