was driving along today an just on boost heard like a whistle then started to struggle with power, cut out, started again an blipped the throttle an sounded like it was off a cylinder, tried to drive on to pull in an stop, stalled just as i got into a wee road
checked all top pipes that i could see an all was ok

only thing i done was change the black rubber pipe that connects the inlet manifold to the dump valve, changed it for a new blue one, same shape an size?

any idea's

Sounds like either the boost pipe to actuator,or a split pipe to the dump valve may be intercooler pipes,doesn't sound much more than that.New spark plugs won't go a miss though. I know you said you'd change one but those blue hoses sometimes arnt the best.
