It starts first time (if a little sluggish) after driving for around an hour it dies, there is no warning or coughing it just cuts out, once cooled it seems to start up again without a problem, any ideas??
Could be the fuel tank pressurizing. When it stops check by opening the tank to see if a vacuum has formed. There should be a tiny vent in the lock to prevent this. Also check the small lead on the fuel pump is on tight .
