I have a early/mid 90's 9.9 Tohatsu 2 stroke outboard, and I just did the throttle advance cam swap on it. Right after I finished doing the swap, I went to the lake to test it out. It ran great for the first 15 minutes, but as I was going across the lake at WOT it suddenly shut off, like someone hit the kill button. It started right back up, and I ran it at 3/4 throttle for about 45 seconds, and it did the same thing. It continued to do this all the way back to the dock, starting right back up each time. It would die after 45 seconds to a minute if I ran above 1/4 throttle. What could be the cause of this? Could it be something related to the throttle cam swap? It seems to me like it is ignition related, but why would it run fine for short amounts of time then all of the sudden die? Any help would be greatly appreciated.
