Post C200 engine cuts

Hi...I am Charles from South Africa. I am having a Mercedes Benz Kompressor C200, 2002 year model. I just got the engine rebuilt and it runs nice except the cutting when it gets hot. I got it checked with Star-Diagnostics and the only fault discovered was 'open circuit upstream O-2 (oxygen) sensor'. The Crank-Position-Sensor and MAF sensor are new, and there is no air leak. Can the O-2 sensor be the cause of the engine cutting ? It cuts as if it is running out of fuel, but when I start the engine, it starts without a problem, then after 3-5 minutes it cuts again. When the engine is cold, it idles for about 8-minutes without cutting.

In my experience a Star diagnosis always diagnoses accurately so I would replace it and see what happens.
