Thanks, Loren.

I did, at one point, turn off the engine to get some groceries. This did
not fix the problem - it reoccurred on the next climb, which was the
last climb of the day.

Thanks, Zoltan -- why does it feel different? The mixture meter showed a
fully-lean condition during shut-down which had me wondering about a
plugged fuel filter, but I could not see a way for it to unplug itself,
reliably, after 3 to 4 seconds of pluggedness. That said, it's not clear
to me why the fuel pump would only pick times when I was driving
steadily at 3,000 - 3,800 rpm, on an uphill to take a break. Although,
with an AT, it's possible it was shutting down on the flats, too, and I
might not see it, although I was paying close attention hoping to catch
it in the act.
