That kind of sounds the way my '53 Chevrolet COE did, when I first got it. Unloaded it at the old railroad depot, & drove it about a mile home, with no problems. From the next day forward, I had the same problems as you. It had done a lot of sitting before I purchased it. I figured it may be a fuel tank issue, so I disconnected the fuel line between the fuel tank, and fuel pump, and ran it straight to a jug of fresh gasoline. Ran like a top again. I replaced the fuel tank with a new one, and never had the problems again.
