I'm haveing the same problem. did you have any luuck when you checked the EGR? I checked mine and it seemed to be opening and closing fine. I did however remove and clean the crank sensor.................after that it went from running 5-7 minutes to running almost 30 before it conked off. I'm replacing the crank sensor tonight (had to order it). I'll post how it turns out. Thanks to all!

 

All very good and all, except the car is in the wrong forum ! I suppose the OP has got the answer, anyway.
