You could have a sensor problem, but it could be someting as simple as a connector issue.

Thanks mate do u know what sensors or connections i should check?

Start with the engine earth.

Check all the sensor connectors, take them off, clean them, refit.

Thanks mate, wher do i find the engine earth? il try all this out first thing tomorrow as this is the only thing wrong with what is normaly a reliable car, it does have the tendency to happen worse when its raining aswel?

OK, if doing it when wet, check the O2 sensor leads and connections.

i had a similar problem with my Mk 2 Y reg punto, only it would cut out if i didn't rev the engine, then i would have to restart the engine while still rolling!

the problem with mine was the throttle body assembly unit. thankfully i was within my warrenty when this happened. but thats my experience.

worth checking out

O2 or lambda sensor is the sensor in the exhaust that looks at the exhaust emmissions and send info to the ECU to adjust the fuelling. Usually found sticking out of the exhaust at 90 degrees thereto.
