Car ran haot and burn up engine.

Over the past several months my 2006 cheverolet Cobalt engine has been cutting off while driving. It will just cut off down to the battery. It started out by just quitting when I came to a stop and then it graduated to cutting off when driving on interstates while I was going about 70 mph. I have been able to pull off on to the side of the road and restart the car. We thought it may have been water in the gas or that the fuel injector was stopped up, but after running higher octane fuel and using the fuel injector cleaner it still was cutting off. It has gotten progressively worse going from maybe once or twice a week to almost everyday. It would not do it for a couple of weeks and then it would start doing it again. We finally took it to a shop and they said that it could be the fuel injector or the O2 sensor going bad. After replacing both of these componets, the car is still doing the same thing. My car has a little over 120,000 miles on it and has been regularly maintained. My mother bought her car around the same time I did. It is also a Cobalt but a 2007 model and it has just started doing the same thing.
