It's just a guess but I don't think the chances would be very high. I think if the O2 sensor was shorted, it would blow a fuse. Electric motors tend to quit running because of heat and heat is caused by it drawing too many amps because the work load is too high or it isn't getting sufficient power or ground. I think I would go with the pump is burning up because it is working too hard. Check all lines and make sure they were totally open and the fuel pumps job is very easy. Check the amps to make sure it isn't pulling too many amps but if it were, you would think it would blow a fuse unless the fuse is not the correct one. I can't believe that bad gas would cause a pump to fail as it doesn't care about gas quality. But I really like Brandon's idea of the screen being plugged and would probably be my first theory as well. I would also check the fuel pressure at the fuel rail and again at the hose going back to the tank to make sure there is nothing blocking the flow. That's the route I would take. What I'm not saying is that the gas doesn't need to be changed as indeed I do think it does but more for the engine's sake than the fuel pump.
