Thanks mit_peid...
That kind of stinks that those things just let go when they die.
Most pulleys just scream for a while making it obvious that the grease or bearings are done.
I'm following another thread by Neal from EQ Tuning in Fairfield.
His metal idler pulley died just like yours over the weekend. Same symptoms, than boom, side of the road.
I think there's only two of them (idler pulleys right in the middle of the belt configuration). The one that self destructed was the one on the drivers side. Yours too?

I replaced the bad idler pulley with a new one (along with a new OEM belt) and have been driving on it for a few weeks now without any further issues. I did have to file down a burr that was caused by the bad idler pulley making a groove on the block after it failed -- without it doing so the new idler couldn't spin freely. Hopefully it didn't screw up any tight tolerances from the factory (I doubt it since I barely filed down anything).
