331 Sputters

[toby5980]

I have a Ford 331 ci stoker in my 1995 Mustang. I have a Holley 650 double pumper and I run 93 octane fuel. My issue at wide open throttle going down the drag way the engine sputters. I know that it's not an ignition issue. It almost seems like it's running out of fuel. It's maintaining 7 psi from the pump. Please help my sick drag car. It wasn't doing this last season and did not start doing it until I had two passes on it this year.

Some more info please?
Carb list number, ignition system components & age.
Do you run a fuel pressure gauge visible to the driver?
Have you had the bowls off to inspect for carb internal corrosion? Gary
