GT engine cutting out HOTstart problem

[cheddarcheese]

my car was fine when i brought it 2 months ago, then after about 2 weeks it started cutting out on me for no aparent reason, then this "problem" seemed to solve its self untill a week ago, i can start my car it will run fine sitting still for 5/10 mins and then it just cuts out, the same happens if i drive it, then after it has cut out some times it will start staright away and others it will not and i have to leave it for 5/10 mins, possible cause for the cutting out?

Can anyone share any light on what couls be causing the problems??
