I have a Bayliner with a Mercruiser 5.7 motor. It it died on the lake and would occaisionally run for less than a minute. I followed the diagnostic chart and it said I needed a coil. I installed a new Mercruiser coil. It starts easier but I have to turn the kill switch off then on and it will start again. It will run smooth for a minute and then start missing and die. If I crank the motor and turn the on/off switch on the quadrant it will start but die after 1 minute. When it starts to die I sprayed a fine mist of starting fluid and the carb. It still dies. I have put 12 volts directly to the coil and it doesen't help. I need help! Thanks, Ted
