2004 Yamaha FZ6 Engine problems

Motorcycle shuts off after reducing throttle during deceleration and during shifting. Many riders of the same model motorcycle have reported the same problem. This is dangerous because the bike is w/o power and sometimes during downshifting the rear tire loses traction and causes the bike to slide sideways. *Nm

1. Bike started and warmed up fine. After about an hour of riding bike was idling very low at a stop sign (800-900 rpm). Power delivery was choppy from a stop also. At the next stop light the bike stalled, and I needed to use the throttle to keep it idling . I shut the bike off at some point, turned it back on and the bike was back to normal. After about 10 more minutes of riding the bike stalled at another stop light. Since first occurrence this problem has been intermittent but usually goes away if the bike is shut off, then turned back on. . *Nm
