You may want to post the question to the RV list since some of the RV's are flying with automotive conversions and some may also be flying at the flight levels.

The test folks couldn't figure it out, because it only happened high up and all system tested normal on the ground. The test pilot went to talk to the Republic test pilot because the P-47 was using the same engine and readily got to 30K. It turns out the ignition harness system on the P-47 was pressurized and the Hellcat not. The lack higher density air, the wiring was shorting out. Many of the bombers had pressurized ignition harness.
