Hello, I would first determine if it is only one cylinder that stops firing. Once you determine which cylinder it is, swap coil from another cylinder and see if the problem changes along with the coil.

Hello 2stroke73, it sounds like the Power Pack may be out. There is also a Rectifier/Regulator that could be causing the problem. I suggest you purchase a repair manual. It will have instructions on trouble shooting the Ignition system.Click Here: Johnson/Evinrude Repair Manual
