What is the fuel pressure at the carburetor tee when the problem starts? Normal is 2.0 to 3.0 psi. If it's low, open the fuel filler cap and see if the problem goes away. If it's high, are there any signs of fuel leaks?
When were your carburetors last rebuilt, and by whom (i.e. you, a friend, the PO, a professional mechanic, a carburetor shop, some kid down the street, other)? Do the piston-like objects inside the carbs move up and down smoothly? Are all the hoses hooked up correctly? Are all the parts present? Any signs of flooding?
Anything special about your ignition system (e.g. non-factory coil, non-factory ballast resistor or lack thereof, Pertronix, MSD, other)?
If you are using points, were they and the condenser changed recently? What is your current points gap, and is there the proper lubricant on the distributor cam?
