2010 genesis coupe randomly disconnecting power on alarm and accessories

[Elphie]

Hi GC community! I need your help my GC 2010 3.8 with push start button is acting weird with its power on accessories. Or my applogies as I dont know what to call or term it properly but for example when I press key fob door lock and unlocked it work first then suddenly its like the battery was cut off that it wasn't being sense by the car. When I try to turn it on nothing happen amidst insert the key fob near the cigarette lighter. But then I noticed that when I press hazard button nothing happen as well and even trying to open the trunk it won't respond at all, but then the door open light indicator in dash board has light which somehow tell me there is power from battery. Normally I would just sit there keep pressing the brake as an attempt to start it and out of luck power goes back on. But then I realized that the red light blinking in center dash stops blinking when this happen, right now im disconnecting the battery and put it back on every time it does that. Anyone can point me what's going on and advice for fix would be of great help (sorry for the long post)
