I don't know what type of lamps you have dealt with. I do maintenance for a restaurant chain that has on average 12 lamps per location at 212 locations. All that is in the fixture housing is a capacitor, the ballast and the socket. If the light is photo sensitive it will have the optic eye also. I don't know what you are considering an ignitor.
It is possible that what it is doing is a result of the ballast going bad. It is not the lamp going out. When a lamp goes bad it will not light at all. It is also possible this time of year, if the fixture has a photo optic sensor, that there is snow on the top of the eye housing. It will light as normal but the eye gets light reflected back to it from the snow and will shut off thinking it is day light. Then a few minutes later after the ballast cools down, it will relight. I have seen fixtures that will do this cycle for hours or at least till the snow is removed.
