UPDATE...

Checked the connectors, all seems to be fine, could not get the motor to stumble. Tightened the wires from the battery to the starter and the ground as well. Replaced the coil too, just to be on the safe side. Used the marina's Cannon plug hookup, and still get the same issue. She is momentarily cutting out under load then catching herself. I think its in the distributor somewhere.

What is the control module under the cap?

What does the Hall Effect Switch do that is around the distributor shaft?

At this point it seems to be cheaper to replace electronic components than pay the $89.00/hr for the marina mechs. I am friends with the mechs, and they have been very helpful, but everyone is still stumped.

New problem... I have a 454 MAg in a Donzi 22 Classic, When I hit a wave, the motor momentarily cuts out... then catches itself? I cannot seem to recreate the problem except out in the water...

HELP!

Sorry I don't know your experience! are you hitting the rev limiters? If not start looking at all connectors.

Sounds like where the harness plugs in, the cannon plug. Twist the plug, move it around while idling and see if you can make it happen. Sometimes the clamp on the plug is tightened too much and causes a problem. I think you're better off without the clamp, but make sure it's not too tight.

Second the main harness conector. My old boat would do exactly what you describe. Grab it and twist it around while the engine is running. If it stumbles thats your problem. If so remove the plug and clean the male prongs. Then expand them a little and reinstall. If still loosing contact I have found that twisting the plug a little to put it in a slight bind then tightening the clamp will make the connection more secure.

Had a friend with same problem. His was a loose wire from coil to distributor.

jollyroger,
Everyone here has some great ideas on stuff to check. I also encountered the same type of problem in a 38 Cigarette once. After checking out evrything on the engine time and time again it turned out to be the purple wire on the back of the key switch under the dash. Everytime we would go over a large wave the engine would cut out but start right back up again.
Also if you have a carberated engine the float level could be alittle to high. This is popular on some Holley carbs if not adjusted correctly.

Good luck in the hunt !!

Just a thought-----have you checked the cut-out for the shifter linkage?
Could the linkage be "bumping" or the switch be actuating during high "G" landings?

Did you wiggle the wiring near the
helm area, while running ?
Did you check the kill switch ?

The shifter should not be the problem since your on the "running" circuit. The kill switches are notoriously bad jump these for sure. Next hot wire power direct to the ignition system, run a switch upfront so you can kill it. This will isolate a power wiring problem from a true ignition problem.
