Fuel pressure? Looks a bit like that. Have you read out the ECU fault memory?

Does it matter if the engine is cold or warm? I have (had? have replaced the pump but no long-term experiences yet) the same problems on my 220V (3B) - when it's hot, it starts excellent. When it's cold, it starts well - but when it's warm, it requires me to start for up to 10 seconds until it comes up. But it runs well afterwards. When I start, turn off again, and start again it starts immediately - as on your video!
