Need some ideas on what to check as the cossie cut out on me today.

2nd gear, full throttle and it just died. Just as if it cut the ignition.

Its not boosting high enough for it to be the overboost cut-off and the pectel monitor didnt indicate any sensor faults at all. Got a indication for the crank position sensor earlier today but none when I got this cut off.

A bit puzzled on what to look for?

Can the intake hose collapse?
