Another 70 that quits sparking when warm

[dufrain]

I have put in new points,new honda condensor and swapped out coils with another used one.This thing runs like a new one for about 4 or 5 minutes,then dies,has really weak or no spark.Let it sit for a few minutes and it will start back up and run perfect again.After it cools it has a good hot blue spark.Anyone have any Ideas.thanx

Did you change those parts because of the problem or started after the change?

I changed the stuff because of the problem and it doesnt seem to have helped .I am thinking it must be the main stator coil.It seems like the only thing left
