any theories, flame ignites then suddenly shuts off tripping the fuse box on potterton lynx 2 boiler?

Answer:

I am assuming you are UK. There could be any number of things causing this and when you say it trips the fuse box I am assuming you mean the earth leakage trip so everything goes off. Have you checked around the boiler its self for water leaks or possibly cable damage. You can remove the outer white casing as that is not a safety issue but turn off the supply to the boiler first. Look around the boiler for any sign of water where there shouldnt be any as it may be dripping onto electrical components or check the wiring harness as it may be touching the boiler somewhere and causing an earth fault. Cannot really help more than that as I cannot see the boiler.
