Aqua-Medic ballast question (250w hqi)

Hey all!
I am possibly going to buying a ballast/light combo from a seller on here. He says the ballast is screwing up, but might be fixable. The ballast will strat to fire the bulb, but will start making a "thumping" noise 15 seconds into it. The ballast will still be on, but the bulb will not stay lit. Any ideas what is going on?
Thanks a ton!-Adam

"i will tur nthe light on, it will light up and start to warm up. about 10-15 seconds into the warm up the ballast will start to make a fast thumping sound and then the light will turn off. the ballast is still on, but the light isn't"

Go MIAMI!!!!!

sounds like the ballast needs replaced. might want to consider the difficulty of ascertaining this ballast before buying the fixture.
