headunit and gauge cluster problems

[staygold24]

Hey guys I have a 95 s14 but alot of the time my headunit just goes black and the gauge cluster clock dims darker and darker. then some times it will just jump back on but only for a second. this is very frustrating when i try to listen to music and it only plays a 3 second clip every minute. If yall have any ideas let me know.

Thanks,
Will
