Your description makes it sound like the cylinders were seizing in the bores. They shouldn't be, obviously. I wonder if you are running 105mm cast-iron cylinders? I have heard stories of the large cast-iron cylinders distorting given time and heat cycles, and that could possibly cause symptoms like this.
Any way you can talk to the builder of the engine?

Dave,
I agree that the oil temps seem to just fine. It is just weird that around 210/220 the engine appears to seize???
I did check the cylinders and they are magnetic and they have a reddish oxide. So they could be cast-iron. I will call FAT today and see if they can remember what they might have used back in the day.
Thanks!
