70 LeMans Sport w/ 455.

[ATKRON86]

So I'm relatively new to owning a muscle car. I owned a 70 LeMans Sport in high school in the late 70s.
Bought this one in 2020. Last year she was in the shop having some interior work. Since then, driven every 2 to 3 weeks. Today, was a tough cold start, but it did. It ran for a few minutes, sounding somewhat rough, but warming up, went inside for a minute and heard it stall. Haven't been able to get it back running since. It's so close... just doesn't. I tried some starter spray with the same close but no cigar results. Any suggestions?

Nice car!
What are you running for a carb?
Could the choke be stuck closed?

You have a Holley.
Did you remove the float level plugs to see if there is gasoline in the bowls?
Did you check if you have spark?

Open the throttle quickly at the carb and observe if you are getting an accelerator pump shot, if so, you have fuel at the carb. If not, possible fuel pump or supply line issue or maybe just low/no fuel level in the tank. If you have fuel at the carb then carefully check for spark. Another way to test is to give her a small shot of starting fluid, if she fires up and then dies it would indicate you have spark and the issue is likely lack of fuel.
