my boiler keeps switching off and I have to reset it, I can run my water for 2mins and my central heating for 10 mins.

As I have no reference manuals for this boiler I can only be vague.
Something is breaking down under 'load'
As you get water for 2 minutes and heating for 8 (heating fires up at a slower rate), I would suggest the pump is failing, running too slowly.
It could also be the fan, but that would break down on hw and ch more evenly
