A little late but, I have read of departure accidents that were caused by water in fuel, in the right conditions, ( my first thought tanks 1/4 full on one ) scenario, pre flight and sump tanks, ( this does not remove water droplets on top of tanks ) then you taxi and take off with the fuel splashing and now those water droplets are now on their way through the fuel system. I always rock the wings before preflight to get those droplets off the top of tank and then sump at end of walk around preflight inspection. is there a big temperature and humidity delta, night-day in your area?

I had something similar today, and think it may be the fuel boiling off in the F/I fuel divider. I am still in the run in period and my CHTs have run high. It was fine once I lowered the nose and got the CHTs down a bit. A second flight today I left the electric fuel pump on during climb and also climbed at a higher airspeed and did not experience anything unusual.

I am using a plenum and the fuel divider is pretty close to the case so it may be more prone to this. Hopefully temps will come down a bit more as the engine breaks in.

I have seen this happen because of a loose rotor tab on a Slick mag. it was intermittant and would briefly stumble the engine.

That should cause a slight loss in rpm though, right? Not a full power loss? I've had an in flight mag failure before and this was definitely not that.

Here's a direct link on Lycoming's website.

I had the exact same symptoms and it was the exhaust valve on the #3 cylinder, which always runs hottest.
