it might actually be the O2 sensor  (for once)
sinc it takes a little time to occur (the ECU adjusting to the incorrect signal) and only happens during cruising..
check that wires have not been detached perhaps, and try to get a multimeter onto the O2's output wire to se what it is doing when you get the hesitations.. on cruise it should be flicking between high and low voltages (maybe 0.8/0.2V?) as the ECU adjusts, but if it rails either way, the ECU may be overcompensating..
