I'm no longer able to get any kind of restart going in the air. If I do a split s and cut power to idle while inverted and pulling positive g's (not negative) the right engine will flame out 25-50% of the time. Once this happens, I can no longer get this engine restarted, even with the JFS. The starting sounds also seem to be playing in a loop, with the 26-50+ percent engine rpm sound effect. Spent a good 30 minutes troubleshooting with no luck.
