Hi I have a fiat Doblo 1.9 JTD 120 BHP the problem is once it warms up about a mile driving the engine keeps cutting out if I wait about 10 to 15 minutes it starts again only to stop a short time later I have changed the fuel filter but its still the same or in face getting worse as it starts cutting out now even before getting to the proper temp, any help would be much appreciated also my backbone has come off I have a new one but have not replaced it yet the problem with cutting out started after the exhaust back box fell off
