[QUOTE="Pappy, post: 452321, member: 3278"] [size=5]Inside the power pack is a printed circuit board. As the pack heats internally and absorbs more heat from the running engine (heat soak) there is a chance that a printed circuit or component on the board can go electrically open. Once cooled the connection is restored and will serve you again until it, once again, reaches some heat threshold and opens. I have seen it numerous times on any brand of engine, none are perfect. I have also had it happen to my own personal engines once in a while. Am assuming you have ruled out fuel by pumping the bulb and verifying the carb is full. When the engine is experiencing this it would be easy to troubleshoot with testers or in your case simply check for spark. Verify that any kill circuit wiring and connections are not worn through and or touching ground. Clean all grounds for your coils and your power pack. Once you have verified spark (lack of) the likely culprit is the power pack. Worse comes to worse you can carry this old pack as a spare that can get you home a little at a time! [/size] [/QUOTE]
