I had this problem with my new Musso years ago. Turned out to be the vacuum hoses, which had shrunk and come apart at one fitting. Loss of vacuum = engine runs on.

I have exactly the same problem with my 2005 Musso Sports at the moment.
I have managed to rule out any electrical fault, and have now narrowed it down to being a problem with the vacuum hoses.
I have replaced all hoses showing signs of cracks or splits.
The only part I have not checked is where the vacuum hoses go through the bulkhead into the back of the dashboard. This is where the ignition switch is linked to the vacuum system.
Please let me know if you have any further information.

Does it have a turbo timer? If it does, it should only run for about 5 minutes tops.

The vacuum pipe has come off the valve on top of the diesel pump; just look for a loose 3mm black pipe.

Check the vacuum pipes.

Have you had any luck with the engine switching off?
I have a 1997 Musso diesel (non-turbo) and the vehicle started giving a similar problem. And no, it is not because of cold weather. This happens after driving for 20 minutes. Also from SA. The electro-mechanical advice is to install a cut-off valve. Seems spare parts for a new ignition switch are also difficult to find.
Thank you.

This may have a turbo cool down system installed. Most turbos come factory fitted with this type of system, they will usually turn off after a short period of time. If you are concerned, get it checked by a decent mechanic. Hope this helps.
