Hi was driving home from work yestarday was driving for about 10 mins then car started to stutter engine felt like it was going to chuck it started to loose power stearing then engine stoped.Tyred to restart engine it would turn over but would not start.Left it for 10 mins then started first turn,got it back to house engine was running as nothing had happend.Went to work next day car broke down half way there same again but this time engine would not start back up had to get car towed back to house.Someone suggest i get diesel as the gauge was low but i knew it still had plenty of fuel in it so went and got diesel put it in then it started first turn so i left it running after a few mins engine cut out again.I have tryed changing fuel filter still no joy.
I have noticed when i turn the ignition on the glow plug lights go off then when i try to turn engine over the glow plug light flashes does anyone know what can be wrong with engine.
Do i need a new pedal assy.

UPDATE - Went out to car this-morning started first turn so i let it idle in the driveway it ran for about 4 mins then cut out.

Thanks in advance any help would be great.
