Smile trouble shooting, they call it shooting because sometimes you want to use a gun!

Is the pick up in the bottom of the tank? Is the electric fuel pump to hot when it runs? I know they get warm when running but hot? Get a gas can attach a fuel line and see if it will pump 4 or 5 gal of gas. Get it off the carb or close, that way you will check the fuel line from the rear of the car. I wonder if it is the heat or the time that is the problem. Does the fuel pump get hot and fails or the fuel line/pick up in the tank stops up? Does the engine heat the carb till the fuel boils? Faulty regulator?

Hang in there with us, we will figure it out. Your correct, it's something simple.
We had a friend tell us that when he stomped it at 40 to 50 mph it would miss, spit and sputter. We check under the hood and found the air filter had two pounds of dirt in it.
Another friend had a miss at 2800 to 3800 rpm. We talked and looked swapped parts for 4 or 5 months. We were eat one Friday night and our Ford mechanic buddy was there. After we finish we all when outside and listen to the miss in the Cobra. Eddie said change the TPI and make sure you use heat sink grease. The grease was the problem. Lawrence had use dialectic grease before and it may have burned the TPI up. Changed the TPI and used the correct grease, problem solved.
