I dont think air going direct to turbo would cause this. your fuel return needs to be unrestricted as the pump draws far more fuel than it needs, most is returned to the tank at a feirce rate of knots. put the return into a bucket and see what i mean.

also make sure you're using fresh fuel, old fuel is a bugger.

you might be getting air into a fuel line, possibly from the steel connectors on the fuel sender unit or the top of the water seperator. if they are rusted they can pull small amounts of air and has quite a big effect on engine speed

Yep , what they said , FIP stuck open . It will need stripping and cleaning by a specialist . You are lucky it stopped on the key - the last one I had this happen on self fuelled on the engine oil , not a pleasant experience. Having the air filter (& breather) disconnected is probably what saved it

cheers
