Engine cranks up but dies when I release the key to the run position

Likely your man overboard switch is open. The reason you get 12V to the coil while cranking is because that comes from the starter solenoid.

Jumper that switch and see what happens.

If that still doesn't work, you have an open or high resistance between your coil's resistance wire and your ignition switch. Check your engine connector to see if it has corrosion.

My bet is on the man overboard switch though.

After a few hours of checking voltages and changing filters I jumped the kill switch. That was it!! Thanks for your post!
