If you have verified spark.. not just new plugs i would look into DVA testing the electronics.

Could be high speed end of stator..

K.C. Does the motor die just above idle speed, or at say 2500RPMs? If just above idle, you likely set your idle mixture too lean. Richen them up a bit, top carb first and test beterrn adjustments. If it dies above 2500RPM, maybe it is ignition problem.
