Still dying when I slow to a stop

[chrismoore701]

Well this is an addition to a previous post. I am still having trouble. Brand new project. Just finished it and just turned 500 miles and I start having trouble with the motor. When I Slow to stop, it sputters and dies. I have a Chevy 350. Mild cam. Turbo 350 Trans. I have tried and checked everything fuel related. I checked all possible vaccum lines. Rebuilt the carb twice and did see anything. Changed the power valve with a smaller one. I am wondering if it could be the control module in my hei. Any thoughts? At one time I was checking it. It just died. No sputter. Just died
