Sounds like two separate problems:
One, "the electrical went out" but the engine kept running. What does that mean? The lights went out? The battery stopped getting charged? Smoke started pouring out from the headlight shell?
Two, it won't start because it's electric start only. Pretty straigtforward, here: is the battery good? is the starter good? is the pushbutton working? Can it be bump-started?
As was mentioned, we need more info on how it's behaving.
