All ignition system component's age with use, and as compression ratios go up, and obviously even more so in turbo or supercharged engines where the cylinder peak pressures escalate even more quickly, the more quickly the ignition components become unable to "light the fire", sometimes on just an intermittent level. So what you are seeing is not at all unusual or unexpected, and it is also why full race engines resort to multi spark and really high voltage ignition systems. The penance you have to pay for higher HP output on the street is more frequent maintenance and often higher quality ignition components.
