Hi all,
I have a M620, 2003. Since about 2 weeks, the engine dies after about 10 minutes of riding. It first starts coffing, misfiring, then dies and can't be turned back on. After letting it sit over night, engine works fine again, but again only for a few minutes.

Can anyone help or had the same problem?

Many thanks,
Tappo

check the plugs for spark? Could also be a failing fuel pump or simply a clogged fuel filter.

Have you tried popping the tank open when this happens? It sounds very much like vapor lock to me. If it runs after you let air into the tank you may have a simple pinched breather line or clogged carbon cansistor if you still have it attached. I have seen so many bikes that their owners have taken the canister off and plugged the tank breather hose.

Easy to trouble shoot.
