Thanks guys I will certain give all the ideas a go. Someone else has suggested electrical problems - suggested fitting a second earth. I think it is electrical as it so sudden, its not like running out of fuel its a real jolt. I will let you know how I get on.

Thanks for responding Nodge68 and sorry for not getting back to you sooner.. I have a 2006 FL2 2.2l manual HSE with 112k miles. The problem has been there for two years. The engine seems to hiccup or splutter about 10 to 15 mins into a journey 2 or 3 times then returns to normal. No error codes...

Hi briano, I have the same problem had it for 3 years. Did you get the problm fixed?
