I'm pretty sure the backfire in your cat is because you are running lean. I've seen it several times before. Actually, it can come from a leaky fuel injector too. Something in your fuel system isn't pushing enough fuel into the engine, or your TPS is bad, or your MAF is bad. I'm pretty sure it's related to fuel.
I'm not aware of clogged cats cauing backfiring, just a loss of power, and I don't really think it happens instantly. As far as it not being something electrical because it was running so good before, sometimes stuff just breaks, or gets a bad connection. Stuff doens't always run bad before it terrible.
