In general when a engine starts good cold and then has a very hard time starting after heated up the valve lash is probalbly tight.
Very common for titanium valves to do it all of the sudden.
It might not be your case but its worth a check.

actualy not sure what its called but the switch when you depress the clutch lever was pushed up against the bar after i pitched it to the left and didnt allow the starter to turn over . man im relieved that was it...now just got to wait for my collar bone to heal.....
