This one has me stumped. I have an Xtl5000 and xtl2500 in my vehicle. They're both wired through a blue seas fuse block. The xtl2500 has no issues, but the Xtl5000 keeps restarting on me. Usually it turns right back on, but will do this several times in a row. There's no pattern as to when it does it either. I thought it was a loose wire, so I checked all of them. No loose wires. No bad fuses. I also checked all the settings in the radio that might account for it and no issues there. I can't figure out a reason for this.
