Engine Died then came back to life

[Mr_Rich]

I think the idler pulley could be the likely culprit. It's kind of funny since if you remove the belt and spin the pulley it will spin real nice, but the bearings have probably run dry and now transmit more noise into the bracket and engine block. Of course the alt. could do that too, but it would be a different kind of noise. The noise I'm talking about is kind of like spinning a roller skate wheel. That's about the best I could describe from memory.
