Your car is probably overboosting, and security boost-limiter kicks in, cutting fuel-pump. It's probably APC-valve that is failed, blowing air trough. Hint: There is a valve suspended on watercooler with three rubber hoses going to various things. There is also a electrical contact on it. First try to disconnect the electrical contact and drive around. This should force car to run on base boost (middle of yellow). If car stil overboosts then it's the faulty valve blowing trough or maybe sticking wastegate (very unlikely). I'm betting on valve,,, Cheers P.S. Leaking out is not dangerous, but try to fix it before it gets worse.
