It sounds like the solenoid contacts in your starter are failing.  In
the early stages of contact wear, the starter will work intermittantly,
but as they get worse it will engage less frequently until the starter
is completely inoperative.  You will hear one loud  click even when the
engine fails to crank over, indicating that the starter solenoid and
ignition key circuit are working but the starter winding is not drawing
current.

The other end of the spectrum would be an intermittant short in the
starter motor winding that would draw excessive current but not spin
the motor's armature.  This would be accompanied by excessive dimming
of lights as the key is turned to start.

A Few Times I Went Out To Start And It Was Dead.
Nothing...but, The Lights Etc All Worked And Battery
Gage Read A Full Chg.    Later, Tried It Again, And It
Turned Over.    It Was To The Shop, And They
Couldn't Find The Problem.  Now Its Done It Again.
This Time There Is A "click", But Nothing Else.
What Could Be Wrong??????
__________________________________________

Sufficient power does not reach the starter motor.
Some possible causes, in order of probability:

1.)  Poor contact at battery cable post connections.
2.)  Poor contact at battery cable end connections
3.)  Defective battery cables.
4.)  Defective battery.  (The car battery gauge does
       not show the amount of charge in the battery).
5.)  Defective starter solenoid.
6.)  Defective ignition switch (if click is not solenoid)

Good luck.
