The green thing is in fact an air filter, and the fan was wired incorrectly at the factory when it was assembledso that it set up a wierd electrical noise signal which then caused the ECU to close the engine down. Highly frustrating and difficult to track down.
Funnily enough our daddy's boy didnt chip in to help with advice then but glad to see he's making up for it now !!
Cheers,
Tony
