After all, the sun is a spontaneous ball of fire that no one quite understands how it keeps fueling itself.

The fuel is already there and is limited.

I say the fuel is constantly accumulated. The sun has a very strong gravity which attracts even the smallest atoms from the furthers reaches of this galaxy. Space isn't exactly a vacuum with nothing in it.
