Mysterious shutdown

[nymack66]

72,
I will take your tip into consideration also, I have brand new wires throughout this set-up you name it and its new down to the key switch, but still I am not ruling out an electrical problem just yet,however his fuel tank had me worried about this vent issue from day one.
Thanks

if it acts up again, just loosen the fill cap and try again, that should tell you if its the vent. If it runs good with teh fill loose, tighten it back up and see if the problem returns

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.
