What he explained in his post was the same symptoms I experienced with those ballast maybe even the same ballast that said it was the starter the majority of the time and occasionally the capacitor. Those are not typically run capacitors but are to assist the starter in this type of ballast.
The ballast I had with the same issues was not this brand, and it was probably 9-10 years ago that it happened. I thought the capacitor in mine was kind of what fed the bulb its juice while running.
I'm running Hamilton M135s on my Radium halides right now, and they are pretty nice for magnetic ballasts.
