2.2 cdti hand priming then it starts

Hi to all i hope all you lovely people can help me. Here goes, I've just brought a honda accord executive cdti worked ok for a week then problems started, in the morning it starts fine then afer a minute it cuts out so i have to prime it with the bulb then it starts again and will be fine all day asi say it's only in the morning first thing. Please help ☺☺

Sounds like it's drawing air in somewhere or losing pressure.. check the fuel pipework and replace fuel filter with a new genuine honda item.
