rotax 912s engine failure

[wilsron]

In flight the other day, my 912s in my Kitfox 4 went rapidly from running perfectly, roughly for less than a minute, to totally quiet. Multiple attempts to restart were completely unsuccesful. Folded wings after forced landing on highway and towed home to hangar.
Rotax 912s, about 200TT
Abundant fuel in plane, so much so that it flowed out the vents with the wings folded. Drained fuel sample, no debris or water.
Removed Carb bowls, they were full, and fuel gravity flows at a rate that appears adequate to produce power without the pump working.
Removed a plug, grounded on engine and engaged starter- NO spark on either system.
Reviewed Rotax Heavy MX manual measurement values for the ignition unit, values WNL.
Generator coil Yellow to Yellow 1.5 ohm
Charging coil Red to Ground 4.6
Trigger coils .240 .240 .238 .238

Thoughts?

Thanks

Ron
