Hey guys/gals...

This morning my lights have started doing somethign funny....

When power is turned on to them, they start up, but almost immediately turn off. I have replaced both bulbs, but the result is the same.

These are the ballasts I am using.

Any suggestions on what to try?

TIA

I know that you don't want to hear it but it sounds like bad ballasts.

I agree with doc. Very possibly a bad ballast. Also check your wiring and make sure no saltwater has made its way to where it shouldn't have.
