Coolant temp sensor can cause issues normally though you have a dodgy idle as well.

Another common one is spark plugs need replacing.

mine does this once in a blue moon never worked out what the causes are & ive got a new lambda, plugs, coilpacks, i might just change the coolant sensor as these are only about 30 quid i think
