Hi guys I'm really stressed about this. Started the car as normal drove around for around five minutes and then it just switched itself off. Its never done this before. Started her up again drove for 30 seconds then went off again. Any ideas guys? Please help. Thanks

My M30 did very similar, though it would never restart for love nor money after that first five minutes. After advice on here, I cleaned up the coil connections, and the dizzy rotor and all been perfect since.
Other possibles are the crank position sensor, and the coolant temp sensor (blue on the M30).

*disclaimer* having never so much as looked at an S50 I'm not really qualified to answer but it sounds to me like there could be a component overheating in the ECU. Does it get particularly warm/hot and perhaps have a smell to it?
There's a few S50 and general gurus about who will have some good advice but it might be worth at least checking for the above.

Thanks for the advice guys. I'm going to have to book it in somewhere. Seems to be something electrical. So I;m stuck!

Take the inspection cover off the rocker cover and remove a couple of coil packs, look down in the plug bores and make sure they are all dry.

If there is water down the plug holes it would start to missfire and run on fewer and fewer cylinders.. I know as Ive been there with my M50

Get the Crank position Sensor checked out if this is faulty the car will not start.
It could be getting hot and breaking down.

Anything major will show up on a diagnostic. If you dont know where to start looking for problems its worth finding someone who can plug it in

I have heard that when the ECU is remounted on these conversions it can lead to it overheating due to lack of airflow. i guess you could try taking off any plastic or sound deadening around the ECU and see if this helps, if it does then its a good chance this is the problem
