Had one last week that had exact same symptoms you are having and it was one of the plastic fuel pipes at the tank had a minor split in it, obviously enough to make it draw air and run like a bag of shite after a few minutes !!
Worth a go mate.
IIRC i hink Kev has already done the dummy tank. He's go pipes on order, so it's going to be process of illimination.
