Changed throttle boby , air flow meter , coolant temp sensor accelerator pedal switch an when hot engine stalls , but starts with out delay , problem still the same.
Hi.it sound a lot like a ignition coil coils tend to do that if its got a crack it Swell when the temperature rises
SOURCE: I have an engine on my golf that surges and hunts
could be the throttle boddies need cleaning out or you have a vacuum advance pipe loose

The parts aren't really that expensive, it's the labor these places charge an hour. Call around and see who can do it the cheapest, unless you want to do it your self.

There is a small vacuum pipe from the EGR solenoid that was disconnected, by reconnecting this pipe the problems (that I have had ever since I had a new head some 30,000 miles ago from a VW main dealer) have gone away.
