Laurence asked me for what my suggestions might be to your issue, which is difficult not having seen the car at all but I’ll give it a go.
From my experience I would suggest you took a look the Ignition Amplifier or the Coil Outputs – faults on these can cause exactly the symptoms you are explaining which occur as the engine warms up, and then disappear again as the engine cools while being stood for 30 minutes.
It shouldn’t be too much bother to swap these for a working ones.
Hope this helps
