MY 98 neon will start run for a couple of minutes then lose power and stall. It will turn over but won't start for 10 minutes. I was told it is having 02 sensor problems could i just unplug there electrical conection to the 02 sensors and let the pcm run on default settings would this work if it dose could it cause any major problems in the long run? Any ideas. The car has 300 000km and I don't wan't to dump much money into it.

Yes the car will run that way, a friend just bought a '95 with 286,000km and it's disconnected. However it is far from ideal, performance and gas mileage will suffer. Personally I'd cough up the dough for a new sensor, you should be able to find one pretty reasonable.
