Mysterious shutdown

[nymack66]

I took the Boat out today and ran the crap out of it , Happy to report its a fuel issue, As long as I kept the bow down it was ok half way up on a plane the primer all goes flat! I will have to insert an new vent hook up on the front of the tank.
I will post pictures when this is done , for now the tank is below 1/2 as long as I punch it up on a plane it runs just fine 5300 rpm right on.
Its amazing if I held it on 3000 rpm with the bow up the bad boy shuts off completely starts right back up.
I now remember this was exactly my initial thought as I flip the tank around.
