...well that is a puzzle, do believe that your hazards should work at any time...I should suspect undervoltage to the lighting buss because of a old battery and/or a weak connection from 1/0 battery cable to ground and back to the engine...this connection is responsible for 300 cold cranking amps needed for starting~ the under-voltage is the cause of your problem...bad battery and weak alternator and lack of 300 CCA connections is the cause~
