Was driving vehicle in heavy snow, suddenly lost power, the dash light flashed, the instrument cluster needles moved as if the car was starting up. Could not restart engine, would not crank. All other electrical equipment worked. Sat in heavy snow for two hours (no tow trucks available until next day). Suddenly after attempting to restart after many failed attempts, it did. Drove it home fine. Stalled next day on way to repair shop. Had car towed and shop found one code, but nothing else wrong. Drove home fine, ran can for 45 mins, fine. Next day drove for 35 min to work, fine but left work and immediately stalled just like few days before. Towed to Subaru dealer and took a day to figure out was main engine compartment wiring harness. Replaced with minimal charge of $50, even thought three months out of warranty. Vehicle has been fine since then.
