From your description it sounds like a failed fuel pump. You can verify this by spraying carb spray into the throttle body while cranking the engine, if the engine starts and runs longer as carb spray is added to the throttle body, this is very good indication the pump has failed. The next step would be to verify fuel pressure. The fuel pressure test port is on the steel pressure line on the drivers side of the distributor. Advance or Auto Zone should have a fuel pressure tester in the loaner tool program. Check fuel pressure with the key on, fuel pressure should be 55-60psi.
