mercedes se 500 - 1992 - starting problem when warm

hi

I have a mercedes se 500 (1992) - w140

the main problem is that when cold engine starts easily, but after 15 minutes
(engine goes warm) .. engine stops... and will not start again.

I change the
crank pulse sensor,
x2 ignition coils,
check and replaced one fuel pump
fuel filter.

I realised that the fuel supply is shutting off when engine is warm,
as if i spray fuel from top.. engine continues to run.

SO PROBLEM IS THAT FUEL SUPPLY IS SHUTTING OFF WHEN
ENGINE WARMS UP!!

any idea to help please?
more over no dash light are ON... so have no clue

thanks
