Codes P0031, P0051
Toyota Tacoma 2006 113000 miles
Only after a few minutes of starting the car, the stereo, dashboard clock and cabin's lights turn off. 20 minutes later, everything returns to normal. I've already changed fuses and relays. Can someone help me please?

The same happened to my Toyota Tacoma 2006 and it was a poor contact in a fuse located on one of the battery's sides. I closed this fuse's contacts and it stopped failing.

The only fuse I could locate. I’m sure there is also a relay that controls the circuit.
