I have been trying to get the boat ready for the summer. I have found a bad kill switch. Now the boat will run for around 5 to 10 min. then it shuts off. Fuel pressure is at 30 psi running and 40 psi key on engine off. I have had a timing light on the coil wire. The light will stop flashing right before the boat shuts down. It will not start right up. Let it sit for a few min and it will start. I suspect the trigger in the distributor. Does anyone know how to check it or have any info on something i have missed. Thank you for your time.
