How are they failing? Does the engine use any oil or coolant? What kind of fuel mileage are you getting? Do you smell gas under the hood?
I ask because it is not a common thing for O2 sensors to fail that fast. Excess oil use or a coolant leak into the intake could be enough to damage them. Excess gas from a leaking injector or faulty pressure regulator could also do it.
