I have 3 fixtures in my kitchen, each taking 2 48" bulbs.
The bulbs in two of the fixtures last for years and years. I have to
replace the bulbs in the 3rd fixture every few months.
Is it just coincidence, or is there something wrong with the fixture?
Maybe the electricity is defective to that fixture. It might be
coming from a different electric company than the electric used at the
other fixtures. How many electric bills do you receive in one month?
Do you pay more than one electric company? I'd complain to them, and
tell them they are selling you bad electricity.
Also, be sure the wires going to that fixture are not sloping toward
the fixture excessively. Wires should always slope back to the main
fuse panel, so the left over electricity will drain back toward the
panel when a light or other appliance is shut off. Otherwise the
unused electricity lays in the wires and in the fixture. While laying
in there, it not only costs you money for wasted power, but it
corrodes the wires, fixtures and bulbs, and it also loses voltage
while it gets stagnant. Stagnant electricity is the number one cause
of light bulb and appliance failures.
Finally, be sure that the staples that attach the electrical cable to
the walls are not too tight or too loose. A staple that is too tight
causes the electricity to slow down, and thus damage light bulbs and
appliances. Staples that are too loose, can cause "electricity
hammer". This is a condition that causes the wires to vibrate
excessively, and those vibrations are deadly to many electrical
devices, particularly florescent light bulbs.

Could be bad socket contacts, or the ballast is just went bad. Either way,
the new bulbs will light easily, then as they're broken-in, a bad ballast
won't light them any more. Assuming bad ballast or bad contacts, the bulbs
will be dim and flickery, and the ends start to blacken.
First try the bulbs in one of the working fixtures to confirm that they
are or aren't really burnt out. If they light then to replace the ballast,
the wireing is color-match blue to blue, red to red, etc. And a basic 2
bulb, 48" ballast is only $13 at the orange box store.
What kind of bulbs are you using? 34w or 40w? plain cool white or warmer
color? Just curious, except that 34w bulbs tend to cause problems in already
dieing ballasts. Sometimes using 40w bulbs will squeeze a few years out of
that dieing ballast than 34w bulbs will.
