Plausible way for the Sun to lose huge amounts of mass?

So, I'm writing a set of short stories (i.e. in the "Martian Chronicles" format). It was going to be centered around life on Earth through the sudden dissapearance of the Sun, but after surprinsingly extensive research, I concluded there is not even a theorically plausible (let alone realistic) way this could happen. I toyed around with the possibility of mankind accidentally burning the skies, but I didn't like it, so, after some more reading, I found out the Sun is actually losing tons of mass on a daily basis. Naturally, due to the huge amount of mass it's composed of, that loss makes virtually no difference, barely losing grip on us at a rate of ~ 1.5cm a year.

I need the earth's average temperature to reach 274 K (around 0° C) in the first two years, so I calculated that I would need a total loss mass of 8,7x10^25 tons a year for the Earth to drift considerably away from the Sun and the stories to work.

So, all this being said...does anyone know a way that this could plausibly happen? I'm not talking about realism. That went out of the window on day 1.

I've read something about black holes migrating and solar wind, but I couldn't find any more data on it, probably because it ain't worth discussing for real scientists.

Any help would be appreciated.
