My radio has no power. Fuses in car are OK. Fuses in fuse box under hood are OK too but if I take the fuse for the radio and put it back in the radio works for a while then stops. Tried new fuse same result radio works for a while but loses power. Gave up on it and then a few days later the radio power came back on it's own lasted a few days then out again.
are you actually losing power to the radio or is the radio turning off internally? It sounds more like a bad radio to me. You would have ti verify by checking the power at the wire harness in the back of the radio. Does it have power when the radio turns off or not.
