If your carbs have the fuel shut off solenoids, check to see that each one is opening up to allow fuel into the carb. I had the same exact issue as you describe. My car was only running on three cylinders and would start and idle, when I put the transmission into gear, the engine would die out. The problem was the front carburetors fuel shut off solenoid was not opening and not allowing any fuel into the carb.
