Took the mistress out the weekend, 2013, 1700 miles with all upgrades, runs for 1/4 mile then cuts out, no warning, no coughing or spluttering, refuses to start for an hour or so then fires and process repeated 1/4 mile down the road. Turns over ok but refuses to fire. Idling and revving in garage it shows charge at 14.3 volts so I think the rectifier is ok. I don't suspect the fuel pump as cut out is instant, Factory suspect ECU and offered me a replacement to try. I do have a problem in that if I do a test drive and having to tow it home again I can't get it up my sloping drive into the garage 😫. Occasionally there's a smell of petrol when attempting to start ( an hour is a long time at the side of the road!) but plugs were dry and looked good. Last time it ran under load it did sound a bit rough, not exactly a misfire though, idling and revving it garage appears ok. Any thoughts Gents?
