I gave you a very simple procedure in post #50 to check for electrical failure, if that is what the problem is. You have to start somewhere if you are going to fix the problem.
You could use two buzzers or two lamps if you wish.
I'm not a toilet guy but I do run methanol. You may be way lean when the car leaves. I know my carb stuff must be on the rich side at the hit other wise it stumbles. I had one just die at the hit, after richening it up it ran good.
I had the same thought since it has happened before albeit only one stumble. I richened up the idle mixture, and used a smaller bypass pill. No changes either way.
So far I rewired the ignition, removed the ballast resistor, changed the battery, in the middle of changing ignition boxes, moved the starter in case the power post was arcing off a header tube, went through the fuel system barrel valve, checked and cleaned all the grounds, and changed the shift timer box.
