Vac secondaries are not expected to open without load. I put a zip tie on the shaft of mine and could see that rotated on the shaft to indicate they opened.
See picture.
I would be thinking ignition problems for a high speed miss. Use a digital volt meter to check your plug wires for opens. They should show continuity.
