Did the plane just have an inspection? [...]

Define "just". It did recently come out of its annual inspection. However,
it'd had four flights already since the inspection and before the flight on
which this happened. Also, this is the eleventh annual inspection since I
purchased the airplane, so if air in the fuel lines were a normal
post-annual-inspection thing, I'd think that I'd have seen that before.

I can't rule out fuel contamination, just as I can't rule out many other
things. But the one time I had water (not air) in the fuel, the power loss
I experienced was greater than, and rougher than, what I experienced this
time. So I'm inclined to think it wasn't that.
