Thanks for posting this thread. helped me fix my 16yz450fx with only 22hrs on it.  It was the pressure sensor on the throttle body on mine also. part # 2C0-82380-00-00.

Check your TPS you could have a dead zone. (throttle position sensor)

I didn't read the piles of post so I don't know if you checked for fixed issue yet so please save the drama everyone. Anyhow sometimes when you have a faulty TPS you can open and close the throttle (bike off) fast about 20 to 30 times then start the bike up and it will "act" better slightly for a moment or two... This is how I often diagnose these fast before checking with meter.

was it the pressure sensor on the TB? Part #2C0-82380-00-00?  Mine sounds just like yours and want to try that sensor
