I put a new O 2 sensor on Pre-CAT. The car will start right up and go, no problem. After a couple of minutes she shuts right off. It was driven 7miles and in that period of time it cut off 4 times.

Next time it cuts off-shoot some carb cleaner into the throttle body if it starts and dies out-check the the fuel pressure and injection pulses

If it doesn't do anything-check for spark while cranking engine over-No spark could mean coil/s, cam and crankshaft sensors and control module.
