have 05 auto low mile car less than 27k owned since Dec 23. car symptoms stalling in gear at stops not all time, car is dead meaning acts like battery is dead sometimes with no lights on dash or anything else also key fob don't do anything when this occurs and no crank or start like dead battery. i have replaced RCM,crank sensor,ground cable still having issues. pulled into work today and notice after shutting off car all power was lost again popped hood and wiggled wire loom going into relay box and notice lights came back on thought this was a ground issue replaced ground wire but obviously its in the wire loom any thoughts on which circuits i should investigate?
