I know one of our members had a similar problem, 2-years ago, just had the Cobra built in AZ and was driving it back to Washington State, Everything was (Suppose) to be new. The Cobra would run for 45-mins (there abouts) and die, wait 15-mins, it would fire up, and run fine. It turns out (two issues) A semi-coggled in-line fuel filter (Unknown to anyone, under a frame rail, you could find it by following the fuel line). One of those very small glass filters, that can be cleaned, after finding that, the issue was better but still quit after an hour and half driving, that turned out to a coggled fuel pick-up in the tank. I hope some of this will help Chupee, Cheers Tom. https://bringatrailer.com/listing/19...a-and-america/

2:30am EST, something does come to mind, but not really from the pictures per se.

Under the external gas cap, is there a secondary cap underneath?
If so, it should be a vented cap.
If uncertain if you have a vented, or non vented cap, or whether the cap, if found to be a vented unit, is suspect, I purchase an appropriate replacement vented cap and see if that solves the problem.

In addition, while picture 115 clearly shows a billet fuel filter, I'd check to see if the filter inside is clogged.

Picture 123 shows an electric fuel pump, but no fuel pressure regulator, I'd be replacing the pump and adding a regulator after the pump, and a fuel filter before the pump as well.

Finally, picture 114 shows multiple carb spacers, the bottom 1-1.5" may have been required due to the Edelbrock carb currently in place, but the upper "phenolic" spacer needs to be removed and replaced with a simple 1/8" heat shield (just 1) from the MrGasket "3170" kit.
I've been using them on all my big block, and small block powered cars for years without an issue.

If not used for clearance issues, I'd remove both spacers and just use the 1/8" heat shield in their place.

Morning Bill,

Gas cap not vented. Lift the lid and put the pump in.
New fuel filter and all lines were replaced a few weeks ago.
New fuel pump was installed a few weeks ago, not sure about the pressure regulator. Will ask.
The spacer. That was not addressed but will ask.....

Also replaced the module and coil 2 rounds ago. (1 month )
Also did this, route a single steel braided or heavy duty rubber rose fuel-rated hose from the back of the carb. straight to the electric fuel pump or hose connection junction going the the pump. Eliminate the Holley fuel regulator.

Much appreciated.....

QUESTION: I had someone rebuild the alternator and his work was a bit sketchy at times. Could that be the culprit?

Electrical connections to the pump, ground to the pump, the pump itself, all suspect.

Did you run the fuel line, or did your mechanic? Perhaps fuel line to close to starter, exhaust manifold or exhaust, creating vapor issues and air bubbles that can explain the no fuel in carb issues until everything cools down.

You removed the fuel pressure regulator? Need to add a new one just after the fuel pump.

Need to add a fuel filter just before the fuel pump under the car.

Ok, fuel tank not vented, somewhere on the tank should be a vent of some type, this may be clogged (bugs, ants, bees love to build small nests inside the vent tubes), need to have this checked by your mechanic.

Don't over think things, sometimes it is the simplest of items that cause the biggest headaches.

QUESTION: I had someone rebuild the alternator and his work was a bit sketchy at times. Could that be the culprit? AS I wrote that...... OF COURSE NOT... The fuel is the issue clearly.
