The most obvious answers for this question is that you have one of the following problems.
Wiring problems. Your guitar has wires in it, duh. if those wires become loose a signal will not reach as strongly or as often, and you will hear a fading or a cutting of the signal. (I said cutting of the signal because the word clipping usually refers to distortion.) You also might just have a bad wiring job.
Rusty pickups. This is bad. Really bad. You might have rust on your pickups. This only happens when you really really neglect your guitar. You pretty much have to put it in harms way for this to happen. If this happens you need to buy new pickups.
Rusty strings. Not near as bad. You just need new strings. Rust isn't magnetic and that's how pickups "pick up" a signal is through magnetism. Rust on your strings is usually from the oils on your hands and fingers. It also comes from sweat or the humidity of the environment.
The wiring or electromagnets could be showing their age, a connection might be bad, or the pickup's height adjustment may be getting too low. (The closer the pickup is to the strings, the louder the sound generally is; make sure there is still room for the strings to be pressed, and vibrate clearly.)

Flat fading, or nonselective fading, is that type of fading in which all frequency components of the received signal fluctuate in the same proportions simultaneously. Selective fading affects unequally the different spectral components of a radio signal.
