Because of this, and because of that, something happened.
That's a perfectly valid English sentence. It's a little flowery, something you might see in a book, but it's not wrong to use "because" twice. Others might prefer the following:
Because of this and that, something happened.
But it's just preference.
It doesn't sound good. Because, since, for, as are used to give reasons. for your example:
As (since, cause of) ..., 'Because' cannot be used in a sentence more than once.
OR
Because cannot be used in a sentence more than once, for ...
But because puts more emphasis on the reason!
Here is a good explanation.
Sometimes instead of:
"'Because' cannot be used in a sentence more than once because...."
I use a colon:
"'Because' cannot be used in a sentence more than once: it's repetitive and it puts the reader right to sleep."
