Hubble observes stars blinking out and coming back or or dimming and coming back all the time that can't be explained by planets, dust, ect.
The larger stars seem to have longer dimming or blinking events. Beetlejuice went dim for years. The hundred days dark star is many times more massive than the sun.
I too would like to believe "the suns output never changes" but there's too much evidence not to be open to other possibilities.
Plus something scared the hell out of ancient people all over the world with regards to the sun darkening, whatever it wasn't just a solar eclipse and has caused people to remain fearful until the advent of modern astronomy.
