Engine quits running while driving

My recently acquired 71 SS 454 (LS5 engine) has been cutting out while driving it. I thought the problem was with the battery, but I replaced the old battery and still have problems. It seems like the engine isn't getting fuel; it tries to start hard but the engine won't stay running even if it turns over. After sitting for a week or so it ran for quite a while before it stopped again, and the only way to get it to start again that I've found is to wait for about 20 minutes and it will run for another short stint.
I'm still a very new owner, and I don't know what could cause this, my thoughts are maybe a vacuum problem or a fuel filter clog?

Any advice is helpful, Thanks!
