Thanks to everybody for your responses. Sounds like the general consensus is
either water in the fuel or some other fuel contamination. I'm taking the
plane up to LASAR to have them drain the tanks and go through the whole fuel
system. Hopefully they can find something that would explain what happened.
This sure makes me think twice about VFR on top or even night flying.

I will post what they hopefully find.
