I have a Rover 214 (G)
Mileage 167,000

I have a problem where i am driving along and the car just stops. I leave it for 5 minutes then the engine turns over and then it will gradually start. I have changed the fuel filter, put Red X in to clean the injectors which did work for 83 miles without no problem but problem is back again

Any Help please

How about the intank filter? When was that last changed? It could be one of the main sensors, Water temp, crank, etc.

coolant temp sensor?
