65 Barracuda daily driver

Damn, so I had to go to a meeting about 25 miles from where I live and through L.A. morning traffic. The car was running pretty rough, but made it there. On the way home I stopped at a store close to where I live. And then the car wouldn't start again. Cranking, but not starting. From the past times this happened I learned that letting it sit for 20 minutes helps. So I set a timer and after 20 minutes it started again. So, still no idea why this is happening. Just to see if it's the carb, I ordered a BBD from Amazon for 69 bucks! When I took it out of the box, metal shavings were falling out of the carburetor. I'm glad I notices that and didn't install it. I thought it was worth a shot, but nope, haha. Still need to figure out what the problem is. New ideas are maybe the vacuum that goes to the A/C or the ground of the ECU?! It really sucks, because even though I wanna swap the 318 in soon, I still need the car to get around until then, but I don't want to spend much time or money on it.
