Swap an unit that fails with another that doesn't, if the problem follows
the lamp, then you know the lamp is the problem, if the problem stays, then
swap the starter with the another one of an unit that does not fail, if the
problem follows the starter, the starter is the problem and if it stays,
then your ballast is the problem. (note: your setup may not use starters).
If the above doesn't fix your problem, then you probably have a loose wire
and or screw, make sure all the connections are tight.
