electrical question

[mbarre@juno.com]

I am having a recurring ballast problem with kitchen flourescent lights. 
The ballasts went out 2 years ago (2 fixtures) so I replaced them.  A
year later the ballasts were gone again so I put 2 new complete fixtures
in and now the ballasts are going on these new fixtures...   Is there a
wiring problem that could be causing this or are ballasts just not long
term components these days?  Thanks for any wisdome the list can provide.
