Continental A-65 engine stall?

Yesterday, I flew to an airport for breakfast and as I turned off onto
the taxiway, the engine quit. It's never done that before. Re-started
fine. Did not quit when I returned to my home airport. Maybe the
turbulence was enough to fix it

Some history...the plane had been sitting for for several years and I
started flying it again last fall. It seemed to be OK last fall but I
had another issue (that turned out to be a big intake leak that
prevented it from starting) that I now have fixed. So, could this
stalling be something like the float sticking? After I started it, it
seemed to "load up" a bit and took some RPM to clear it out. Maybe this
is a clue?
