Engine Cutting Out! What to check?

Well crap. I thought the whole idea behind that pertronix unit was that you didn't need an ignition box because it provides multiple spark and has the rev limiter built in. I'm going to have to call them then and get the scoop.

Shoot it might I have never used one. I don't think it has Multi Spark Discharge though. 2 Step etc. I will research them so I know WTH I am talking about.:banghead:
