hello, my stereo works great but sometimes when u turn the engine on there is no power going to it. But when i tap the fuse box below the steering wheel it goes back on. whenever there's no power going to it i just tap it or wiggle the box and the stereo goes back on. does anybody know what may cause that. Oh yeah when that happens the clock turns off to.

the radio and the clock are run on the same fuse and you say they both go out together so i would guess that either the fuse is bad or loose. try replacing it and see if that works
