Engine stall after driving 8-10 miles, starts back up just fine...

After warming the engine up, I can drive total 8-10 miles fine before the engine begins to buck and skip... During the bucking and skipping, if I put my foot on the gas it accelerates for a moment and goes back to bucking and stalls if I repeat to press the gas to keep it started...

Another scenario, if I let it coast for a moment without giving it gas and then press the gas pedal, it drives normally for about another 8-10 miles before it bucks and skips again...

If it stalls, I'm able to start it right back up... Fuel PSI at the carb is 8-9 psi. Carb is an Edelbrock 1405 600 cfm and an Edelbrock single plane intake.

Posted something similar in a Facebook group and didn't get very many responses, but a guy did mention something about the possibility of my fuel bowl being clogged or the fuel/air ratio screws holes are clogged and to remove the top end of the carburetor and inspect these parts including the floaters...

Sound about right ? Or should I be looking for something else ?

Another note: Seems like a lack of power...

1st gear take off seems a little slow and I'm not able to burn rubber... If I attempt to spin the tires while holding the brake in Drive it revs but no tire spinning, and as soon as I let off the gas pedal it stalls... Or maybe I'm not doing it right ? 🤷🏾‍♂😂

If that doesn’t work put a good Q jet on it. These are the type of drivability issues that make me hate Edelbrocks.
I hear people knocking Edelbrocks all the time. My Edelbrock is nearly 4yrs old, I've never had a problem with it. I do, and have had a pressure regulator for probably 15yrs.
Maybe that is why mine has been good to me?

What are my possibilities of finding one (FPR) in a scrap yard that will work for my carburated gbody ?

Also, if I cant find one in a scrap yard, would something like this work ? Or if you could show me an example, that would help alot.

I agree with CK80. I think your fuel pressure is too high and might be causing flooding in the carb or blockage in the return line. I once had the same carb with an inline fuel filter which wasn’t sealed properly. If it was hot and I shut the engine off for about 10 minutes the carb would flood. The only way to get it started was hold the accelerator to the floor. Next time you have the issue (road room permitted) floor it. If it keeps running you‘re flooding the carb. As a reference I once had a 396 bored .20 over, big cam with an a Edelbrock double pump, I set my fuel regulator to 7.5psi; it ran great! Never stalled or bogged. The engine with Blue is the 396 with a Holley now. The engine with the Green is the same carb. That inline fuel filter is the one I had to seal; it screwed together.
