BMW E46 318i 1999 , Engine stop immedietly after turned on

I have BMW 318i 1999 E46 1.9L Automatic , 9 moths ago I started the Car but it didn't start Motor work then stop , 2n time it work. This behavior repeated once by Quarter. Also when I go back the Car sometimes seems to going to stop but it doesn't.
In last quarter this happend 4 times , yesterday it happen all the time and engine can't start uless I keep pushing Fuel and if I remove my leg from fuel padal it goes to stop. I tried to let it go for 5 minutes many times for 400m and after 8-10 stops it works fine.

I use Platinum 4 Bush plugs which as book says work for 100K KMs and Its just installed since 15K KM so It seems no problem in it. so Do you think ita a problem in fuel Pump or Fully supply parts ?
Thanks,
Regards,
Ahmed
