I experienced 2 times a similar problem with my Rotax 912s. About 4 years ago for the first time and it was figured out that 1 of the wires of 1 of the ignition boxes was broken close to the connector. The wire was soldered which solved the problem. A few weeks ago it happened again. So I checked the wires but with no result. Furthermore I checked the spark plug leads, spark plug connectors, pull off force, etc. replaced all the spark plugs but no results. Eventually the problem was located by a local Rotax dealer who discovered a faulty ignition coil. The error in the ignition coil could not be detected by measurement but only by swapping parts. Hence it was a real pain to find out. Good luck.
