Hi. I have a galaxy 2.3 petrol 51 plate. Had problems recently with engine dying when braking. Starts fine every time, but as soon as engine hits normal temp, about 70% of the time when braking for junctions the engine cuts out. Becomes a bigger problem when the immobilizer kicks in and leaves me stranded for 15 seconds until door light stops flashing.Car has been on computer at garage but no faults showed up. Thanks, Marty
