hi all.. I have a ducato 2.8 jtd motorhome its a 2002 model on25k.. it has run without a blip over the last 6 years and only recently started playing up..the last few times I have taken it out as I have travelled along out of the blue the engine dies on me, all the usual dash ignition lights come on.. I then put it in neutral,, quickly turn off/on the ignition and she runs up immediately only occasionally but this last time out she has done it twice on the motorway. as I pull a small car behind it is getting dangerous as I might get stranded out in a lane.. could anybody please offer an explanation for this be it electrical or mech. as I can then get some help from the appropriate source.. I had thought it was water in the fuel or something similar but I don't know.. thanks
