Just an up date on my issue with my E30, had to replace the battery on the car about four weeks ago due to the weather, I thought this may have solved the sudden cutting out problem but nearly four weeks to the day it cut out again after I restarted it on the petrol station forecourt, it did it at the pumps, so I pulled away and parked up, left it idling, it cut out 5 times, after each time I'd Leave it 30seconds and it would fire up straight away each time, after idling consistently for 5mins straight I drove it home with out fault, it's doing my melon in now,, any help is greatly received.
