Do the signals work when just the parking lights are on , not the headlights?
Has it ever had any body work , or have the front signal bulbs been changed recently?
it could be a bad ground not allowing enough ground for the turn signals to work with the headlights using up the available ground. you need to figure out whether you can losing the voltage or the ground to the turn signals. it could be a failing multi=function switch as well.
