I turn the dam thing off and leave it for about 5 minutes, turn it back on and its working normally again... but then the same thing repeats itself after 10 or so minutes it just dies again

Any ideas anyone ?
Sounds as though your evaporator coil is freezing up, but it would usually take longer than 10 minutes. Maybe i'm just used to truck ac systems.

This is due to the thermostat or thermistor not cycling the AC comp off and allowing time for the coil to drain off condensate.

I haven't changed a thermostat on an impreza before, but i think it could be a bit of work, as the gas would have to be reclaimed from the system to allow removal of the evaporator box unit to access the thermostat.

Cheers
