Corsa-B.uk - Vauxhall, Opel and Holden Corsa B Owners Club

hiya pretty new to the corsa's so thought id jump on and get some advice if possible.

So the car drives along fine, slightly hottish, when driving normal its fine but in traffic it will creep up to 95-98..(close to 100 any concern??)
48.000 miles, brand new cam belt fitted. everything seems fine. 1 lady owner before hand. limited service history, quite tidy car for a 93 plate

so only just got the car really and am driving it roughly 40-45miles a day. It drives fine and pulls no problem but every so often now it just cuts out!
completely looses everything and the engine management light comes on. Have driven the car the day after this happened and the light wasnt on but waiting
at a roundabout it cut out completely and wouldnt start, no turn over nothing. might of been that it was in drive but being stuck in the middle of a roundabout you kinda of get a flap on ha ha. So yeh any idea's???

will most probably call the garage the light wont come on and they wont find anything.

it kind of burbles and shudders then cuts out...

took it to the garage and they plugged it into the diagnostic machine.. couldnt find anything, said the fault wasnt for long enough to show up on the ecu's log

quite funny though as i picked it up and drove away the problem happened again, struggled to start then when I put the accelerator down it died, guess its pretty much stalling.
popped in some redex to see if that works but reading through posts it seems like it could possibly be a sensor or relay?

was going to change the fuel filter this w/e see if that helps at all, im thinking if its stalling then could be a fuel feed issue. an old fuel line or bits of the fuel tank corroding and coming through.

So yeh still throwing this out, any ideas?
