Random Stall

This was odd. I was going down a hill near my house when the car just stalled. No choking, no lack of power, just stall. Its a manual and I had it in neutral at the time. Even if I had it in gear I cant imagine it choking out on a hill of this size. It was as if someone just pulled the key out while I was driving. Any ideas?

What year? Any codes? It can be a lot of things, like IAC got dirty, etc...

It's a 2000 no codes. The check gages light did come on right after it died out, but I think that was just because it was off and had the key in. Ive had my power steering give out before for a few seconds, but thought it had something to do with me leaving it in neutral while going down hills.
