1997 Toyota Corolla Unknown Problem

Hi there! My corolla is still not running well until now. It will run only for a few kilometer after starting and suddenly it will stop. I change the fuel filter and fuel pump as well as the air cleaner. I drained the fuel tank already, but the problem is still the same. It is a 2E engine with a carburetor. Can you give me a diagnosis with my problem? How about the distributor cap? Do you think it's an electrical problem? Is it possible? Thanks.
