Took out my Proline for its maiden voyage. I launched and backed into the dock. engine started up fine. Idled it while i was waiting for my buddy. All of a sudden the motor shuts off, and when i try to restart I get no power from the ignition switch. I can hear the solenoid when I turn the key but it wont turn over. Then it finally turns on with no prob. After the test drive, i get back to the dock to load onto trailer. and same thing happens. it just shuts off. It seems as if someone has pulled the emergency stop lanyard. All my accessories work. could this be a bad ignition switch or emergency stop switch? any other suggestions. Oh yeah it did this on my driveway about 3 weeks ago, then it started up fine.
