williams 2 turbo
started yesterday on the turbo, basically filled it up at sainsburys as per normal and then it decided to keep cutting out, then ran fine for a bit. then when i turned it off it wouldnt fire again. it turned over just wouldnt fire. left it for a few minutes, and tried again and it starts. but after its beenrunning fine for 10 mins if you turn it off and start it straight away it doesnt want to know. im thinking blocked fuel filter or the fact it doesnt like the stuff from sainsburys any more. it has had no probs like this ever.
