I'm having the exact same problem... I'm running an HEI, no box... I think mine is because of the fuel pump.
What kind of pump are you running?? Mech, electric??
Hey Guys Need A Little Help Here.
I Have A 454 With Msd, 6a Ignition, Holley 650cfm, All New,
So Last Weekend I Was Out In Havasu. Launched Now Problem Fired Right Up. Went Out Past The No Wake. Jumped On It, Still No Problem, Then The Fun Began. Kept Dieing, Pump The Gas 2 Times, And It Would Fire Up, No Problems, Go To Give It Gas, To Come Up On Plane. And It Dies.
New Fuel, From Ampm 91 Oct.
Any Help Would Be Great.
Thanks Guys

I had the same problem with mine. It ended up being the pet cock for the fuel tanks. There was a piece of the o-ring stuck in the T. It would start and idle fine but when i hit the gas it just died. Just my .02. Hope this helps.

are your filters ok?do you have a water/fuel sperator? sounds like water but if ya have a seperator it wouldn't be. check the msd for a ground failure. msd 6a's have a problem with the heavy black ground circuit breaking the solder at the board,easy fix,just pop off the back cover and resolder.fill in some blanks so we can help alittle more.
See I Ran It On The Trailer Before I Went On The Water And It Ran Fine. Revd Idel You Name It.
Mech. Fuel Pump.
After I Was On The Water Is When It All Started.
Now When Its On The Trailer And I Rev It Up It Dies Also.
And It Idels Like Shit In The Water And On The Trailer.

is it hard to start?do you have to pump the shit outta it to get it to fire up?
WHEN I STARTED IT THE FIRST TIME AFTER 3 MONTHS OF SITTING I HAD TO PUMP IT FOR AWHILE.
BUT I ALWAYS DO WHEN IT SITS. BUT THEN IT NORMALLY FIRES RIGHT UP.
NOW ITS A LITTLE HARDER THEN THE NORM TO START.
BUT IT IDELS LIKE SHIT WONT REV, IT POPS AND DIES.
LETS TAKE OLD YELLER OUT BACK AND SHOOT HER.... SHES :cry: DONE
I had the same problem with my boat. It ran fine then started running just like yours and eventually would not even start. It turned out to be a ground failure in the distributor, it fried my coil. Fixed the ground bought a new coil and all is good again.
Check Fuel Presure First It Sounds Like A Fuel Pump
sounds like a fuel system problem to me and I've had my share. Now my electrical issue resulted in it not firein at all , but hey thats just me
