     That is correct. Reseting the comupter, by turning the ignition
switch off and on, will not fix a fuel pump, of unclog a fule filter.
Water in cooling system?  What ever....
    Step #2 - Disconnect the o2 sensor, drive the vehicle are see
if the problem happens again. Obviously if not, the O2 is bad. If
the problems continue, I would trace down the wiring from the
ECU to the Temp. sensor. Easier than you may think. The wires
tend to break right in the engine compartment were the engine
rocks back and forth.
