Hard to really pinpoint. I have seen carbed engines with fuel issues that will start then suddenly die as the fuel bowl dries up.

But I think you are looking at an eletrical issue. Bad ignition switch, loose connection, failing ballast wire, failing module (if eletronic), etc.
What I think is happening is it will start with the bypass wire (I terminal on solenoid bypassing the regular ignition delivering full power to the ignition system to help start ups). As long as you are on the key in the start position with the solenoid pulled in, it will run.

What you need to do is take a test light with you. If it happens again, check the positive post of the coil for power with the key on. No power? Start following it back until you have power. Easier to search out with points. Eletronic starts the same but has more parts that can go bad.

Coil are generally oil filled. If they leak then they need to be replaced. They aren't designed to vent.
