Hi,

I had the same problem on a Range Rover with Bosch fuel injection too. Turns out that there is a g-force activated switch that will cut the fuel supply in the event of an accident (rapid decelleration). These are known to go bad and cut out while cornering. You should check your wiring diagram to see if you have one they are often under the drivers seat. If this is the problem the fix is really simple (solder a wire across the terminals).

Hope this helps,

Nicholas
