Warning lights on Vauxhall Zafira 1.8?

Hi, I have 3 warning lights that keep coming on intermittantly; exhaust emissions, traction control and engine electronics.

The lights come on regardless of the speed I'm going or the weather or road I'm driving on.

Now when the lights come on the car also stalls whilst I'm slowing down or waiting at junctions. Am concerned as have never had anything like this happen before.

The car is a 1.8 vauxhall zafira 53 plate. MOT'd and serviced october '07. Has been doing this for the last 6 months on and off.

Please help
