Mine will do this when its really warm out and I have the same guess about the ignitor. I'm going to borrow the one out of the clone I did and see if it changes mine. Possible its a valve sticking too. I did clean my cooling fins and it helped they had dirt in them. If the top rocker cover leaks oil it will fill the fins with dirt and plug them. Yes ignitor is pricey for sure. See the timing is advanced about 30 degrees all the time, at low rpm under 2500 the ignitor retards the timing to near 0 degrees at start and ramps up. So I think it stops doing that or something because mine will run ok if I hold it on the floor and get the rpm up, then it cools some and is ok. The odd thing is I've run for a bit then it starts missing and bogging for a ways then stopped doing it, and I went miles after that with no problem....going down the same road and same speeds.
