Default Engine dies during Running 8 pushover

I went out a put a few flights on my new Kaos today.

Only bad thing... two deadsticks. Both happened the exact same way. I was up high and started a Running 8 by slowly pulling back the throttle and pushing over. Before I even reached the bottom of the loop the engine would start to hiccup and was dead by the bottom. I plan on re-plumbing the enture fuel system to eliminate anything obvious. Is this a symptom of an upright mounted engine, a setting or something? Could the low power setting and the negative G's cause the fuel to fly out of the carb instead of being inducted? I could fly all around the field inverted and the engine ran like a top. But the high negative G pushover kills it. Flying from inverted and pushing a half outside loop, it's fine (at full throttle). It's just the outside loop from the top while retarding the throttle. I'm perplexed.

The Evolution .60NT is a pretty simple motor to run. Gobs of power... just this one problem during this maneuver,

Any advice would be appreciated.
