I'd go with what he said, sound very similar to what happened to my wagon. It would cut out and after a few miutes would start up and run fine for a couple of months and then for no reason cut out.....................thought it might be a knackered fuel pump so had a Walbro 255 fitted. tw months later cut out again. Any hows after chatting with the local specialist and folks on the Hants forum we decided to by-pass the fuel pump side the wiring in the immoboliser and ran fine after that
