sounds like you may have been affected by the silicone fuel outbreak last month. Try looking up about it online - it's side effects to certain cars are that the engine cuts out and that its hard for mechanics to detect whats wrong (something to do with oxygen sensors or something). It effected mainly fuel bought at tesco/morrisons in south

multiple choce answer this one i'm afraid.
although the plugs are new, it doe snot mean they are 100% working...never assume that because something is in a box and new that it is ok,
blocked airlines (breather pipes) dodgy leads, some module on its way out but not bad enough to show on the test, bad/loose earth connection, bad fuel, fuel filter clogged....and these are just a few.
if you are half competent under the bonnet, just do a general check on the easy stuff, plugs/leads/distributor cap or whatever is in there, make sure all is tight and clean....if all seems ok then give it a good run before taking it for another diagnostics check (i assume this was a computer test, not just an emission test)

try your "air flow meter"
Theses tend to go faulty on the astra g (mk4) and can cause unsmooth running and hesitation.
Probaly cost around £50 to replace but i would definetly go with that.
Nothing will show up on the diagnostics machine's unless a fault occurs and a warning light come's on your dash console.
If that happens your car will probaly go into limp mode so turn engine off then back on to reset the fault and take it to the dealer were the diagnostics machine will pick it up as the fault would of been stored.
Goodluck friend!

Fuel filter if petrol been low or as lots have people have said the crank sensor but buy on from vauxhall ours went on our calibra and bought a none Vauxhall own make and played up and as had to fit to car before found out didnt work couldnt return as mechanic had mark it whilst fitting it.
Not his fault tho as only part plastic.
So try other easy steps then diag at garage paid £15 for mine them paid Vauxhall £70 for part and fitting.
Might have been dear but felt at time that fed up catching bus etc just wanted car back working.

I once has an old Vauxhall.. It would go for about two miles then come to a halt...
turned out that there was a blockage in the fuel tank...( a leaf or something)... I blew the air line down the fuel line into the tank and it seemed to clear the blockage...

there are a few things i could be, i really needs looking at a garage , the most common things are throttle bodys getting cloged up with carbon, causeing the idle valve to struggle to keep an idle normaly causing it to cut out at junctions ect, the other is a fulty crankshaft sensor. try cleaning the throttle housing first

Sounds like you might have some rubbish petrol. Don't go to supermarkets to fill up. Fill your tank with a reconised brand to dilute the duff stuff. If you still have the problem it sounds like you may need the fuel line cleaned or you have some goop in the tank blocking the exit.

some good suggestions have already been made. although code reader should indicate faulty item. maybe it cannot detect intermittent faults. i'd examine ign amp module and coil/coil packs also ecu. useing substution to eliminate suspect parts and narrow field. one company hires out units for this purpose was £30+ carrage and vat. (per unit) guaranteed next day delivery.

Yeah must be the petrol thing that those 2 were on about, because that's been the only major motoring story lately.
