Because its cranking and cranking when it tries to start up, a lift pump dead enough to cause this would no be able to run the car at all. Its the hp struggling to hit 298 BAR, this is then confirmed by the fact a standard car is cutting out under load in 3rd and 4th gear, its a badly worn hp pump and if he were close to me I would fit one for free for him if it didn't fix it I am that sure.
I work on commonrails ever day, I see these issues all the time and it looks very clear cut
The reason it doesnt cut out each and every time is that there is quite difference allowed between requested vs actual pressure and it would be hard for a standard car even with a worn pump to hit such a difference, hotter fuel will significantly increase the difference. Map the car and I bet it will cut out every single time!
