Id say wiring issue. Do you have one of those plug in testers?
U could run a new circuit from the main breaker board...n that really is the only safe solution to ur issue imo.
It's ur choice not to... As u r renting.... But that being said I've rewired many houses I've been renting, and depending on the circumstances I either put the wiring back the way it was when I moved out or I didnt (if it was a shithole)...
Good luck, I never mess with running 1000s of watts without setting up the circuit myself... Only way to know for sure it's done right.
