Started it today from cold it run for 5 minutes and cut out on me and it did the same as the day before, the engine was just turning over and not firing. I left it for 3 hours again and it started first time. Any ideas?

Is it getting fuel? Does it have spark? Is it flooding? How are your ground connections? How are the battery connections? Do you drive it frequently? How many miles on the car? What has been done recently to it? Is it maintained? How is the fuel filter and pump? I would suspect an electrical issue if it just cuts out instantly, but could be other issues. Give a brief history of the car.
