You could have sediment in the tank possibly clogging the pickup. Did you replace the pickup and screen?

its a fuel relay had the same thing. its a small donut with a set of wires that tell the brain how much to send. the relay is on the back of the carb on the block. I replaced mine and what a world of difference.
