68 Fairlane possible fuel delivery issue

Hello, new member here. My name is James. I own a 68 Fairlane, formal roof, 302 C4, 56,000 miles. I've had this car for 20 years. It was my grandmother's car.

So my car left me stranded, AGAIN! The first time it happened was in 2003. Same scenario as last time.

1) upper 80s/ lower 90s ambient temperature
2) Engine had been driven at least 10 miles
3) Engine had been running fine for days prior
4) Idling for 2-3...
