The ballast isn't connected to the PC is it?

How old are your PC bulbs? Modern ballasts generally do not require a separate starting unit for the lamps, it's incorporated in the ballast circuitry. Also, some newer T5HO ballasts have what is called EOL (end of life protection) which will turn off the lights shortly after start up if they are worn out or close to being worn out. Not sure if PC light ballasts have the same feature, but might be worth trying a new bulb(s) to see if that fixes the problem before you start looking for a new ballast.

The MH and PCs should each have their own ballast. One for the MH and one for the two PCs.

The PC one must be internal. I'll look at it again tomorrow.

the pc ballast is internal in the coralife lights. some have 1 ballast for each bulb some have 1 ballast for 2 bulbs

Thanks. I'll take it apart tomorrow and see if I can get new ballasts.

Don't be surprised if all you find inside the light housing is a couple of transformers and other small components wrapped in heat shrink. I could be wrong though and there may be a generic flourescent ballast (or two) in there. Have you tried new bulbs yet?
