Cory,
I'd be willing to bet your fuel pump is dying. The '84's are known for this.

Check the easy stuff first. Replace the fuel filter. If it has been awhile a tuneup might be in order. Plugs, cap, rotor etc.

No way, it's gotta be the girl. Get rid of her and all your problems will go away. :D
Sorry, couldn't resist.
Couldn't hurt to do a general tune up with plugs/wires, cap/rotor. fuel filter and whatnot if you haven't done it in a while. But it could very well be the pump as others here have said.
Whats the stock output pressure on an 84 pump? Don't the L98 and LT1 pumps put out more pressure? If you have to replace the pump, I'd think going to a higher volume pump and installing a pressure regulator would do nothing but good for the Cross Fire injection...

Heads, cam and the whole rest of the long block is untouched since manufacture. I have ported the begeezus out of the manifold, and bored the TB's to 2". 6000 seems to be the optimum shift point at this stage.
