Radio
The after market radio keeps turning on and off
What testing have you done? Check voltage and ground when problem is ongoing. The two fuses in diagram, one is hot all the time for radio memory. The other fuse goes hot with key on, to operate the radio. Use a test light at those fuses when problem is ongoing. The bottom wire, black, far right is ground, check that also. If good voltage and ground, then I suspect radio.
