1996 Evinrude 150 - only "runs" with key in START position and starter engaged

Howdy ya'll,

It's been a minute. I've got a good head-scratcher for you today. I have a 1996 Evinrude 150 Looper and was out running a few weeks back and the motor suddenly shut off and would only "run" with the key in START position (in other words, I got stranded and had to get a tow).

I've had a number of various issues over the years, all of which, with the help of forums like this one, I have been able to overcome and get fixed.

Prior to this the boat ran great for the last year. And it was about a year ago I replaced:
- stator
- regulator
- power pack
- coil wires
- plugs (Champion with proper gap)
- fuel lines
- fuel primer bulb
- Visually inspected VRO pump and was fine

Since this issue a few weeks ago I have
- Rebuilt carbs from plate forward (so didn't have to re-do link and sync)
- replaced OIS eye
- disconnected black wire with yellow stripe at ignition switch to see if boat would run, it made no difference
- replaced fuel filter

Really the strangest thing and I am stumped. I tested the orange/orange-blk wires from stator and get 56 OHMS. Big yellow wires from stator have 0-2 OHMS. Both of these appear to be in spec.

Has anyone experienced this type of issue? Any thoughts on what to test/check next? I believe it is an ignition system issue based on what I am reading but am unable to pinpoint any faults. Thanks in advance for any thoughts and suggestions!

??I think if the engine was running, it would kick the starter gear back down. If the starter was engaged with the engine running, you would get a nasty grinding sound. Sounds offhand like the "run" position at the switch is not getting current.

Either the charge coil (org wire) are not putting out voltage when running, pack bad or wiring for power coil bad.Check each wire to grnd.
