I realise this is a bit vague, but here's the problem:
Car is a Focus 1.6 Tdci, 2007. On Saturday I set off on a journey of about 15 miles. 2 or 3 minutes later the car just died. I switched off and coasted in to a layby. Tried it again and it started then behaved normally. Returned home about 4 hours later and just as I braked for my entrance, it died again. I coasted to the end of my drive and switched off. Tried again on sunday morning but nothing; turned over OK but no start. Started normally this morning and went (about 5 miles) to my local (small) garage where they plugged in some kind of analyser but reported no error codes showing. I drove back home and, as I braked for my drive, it died again; repeat of Saturday's behaviour. I'm not sure what to do next, whether a visit to a Ford Main dealer would be worth it?
Regards and thanks in advance
