I"m trying to wire two dual 40w fluorescent light fixture in parallel

and an electrical ballast. If I wire each one separatly then it'll
work. I gather the reason might be interference between the two
ballasts but I want to hear some expert opinon.

Odd.

What do you mean "without success" ?

So each ballast has a black wire and a white wire, and you hook the two
blacks together with the black supply, and the two whites together with
the white supply and one or both fixtures does not light? Or they
flicker?

Did you make certain to wire the ground securely?

Are both fixtures the same brand and style of ballast? If not, you
might risk reversing the leads from one of them, but really it should
not matter.
