Fault code was for oxygen sensor. Could that cause the problem ?


That would not shut the engine off. Maybe it is a fuel delivery problem. Check the fuel pressure.

Thanks Mark. Fuel pump or fuel pump relay switch? Its only happens randomly. Seems to be first run in morning. Just loss of power going up a slight hill out of town. car is in top gear but seems sluggish. Not normal. Drops back to 3rd gear and then no power. My local mechanic is at a loss to the cause of problem have recently installed new crank shaft position sensor.

Not THAT Mark.... Check for an intermittent MAF sensor, as you're sporting classic symptoms.
