Got a problem with my fez, Made a 160 miles round trip at the weekend which was fine, then when i left the motorway and parked up in a garage to answer my phone the car was turning over fine, when i left the garage went round the roundabout fine then hit a dual carriageway and then all of a sudden

when i put my foot down the car started judderin like it was either chokin or runnin out of petty then it just died (as in stalled) so i gathered lack of petrol even tho i still have a third of a tank.
Any body have any ideas whats wrong.
i.e fuel pump or filter,
And no i havent filled up at a silicone enhanced supermarket petrol station,just a TOTAL + SHELL
Cheers.
PS - sorry for the essay
