Freelander Starting Problems

Hi, I have a landrover freelander Td4 2002 with 89000 miles, Im having problems when trying to start to the car. In the morning it starts first click no problems, If I start it within 5mins of turning it off it starts fine, BUT if I leave it for say half an hour it just turns n turns for about 2-3mins then it finally starts over.

Since buying the vehicle I have had to change the battery, the viscous coupling, The alternator exchanged, Re Gassed the aircon, The vanes in the turbo had seized up so I had to recondition the Turbo. The little vaccum on the side of the Tubo has been replaced. The 2 rear window motors has been changed.

Iv had a lot of bad luck with this car, I hope someone can help me try and diagnose the starting problem?????

Touch wood I HOPE I dont have any other problems with anything else,,

Please can someone help??
