Hey guys, thanks for the replies, I had already unplugged the Insta-hot to rule that out. Also, the breaker, which is a 20 amp, trips immediately signaling a short. I have a spare breaker that I will swap out today and see if that fixes it. It's strange because I have unplugged all devices from the affected receptacles and it still trips immediately. It almost makes me suspect a chafed or chewed wire caused by rodents.
