YJ 4.0 Idles Great - Stalls or Labors Under Load

I have a 1992 Wrangler Renegade with a 4.0, automatic. The jeep idles great, but when I put the wrangler in drive I loose all power and the jeep almost stalls and acts like it is starving for air or gas. It has virtually no power when in drive. When in park I can push on the gas and she revs up just fine.

Here is what has been done so far.
replaced the following:
Air Filter and PCV
plugs and wires
cap and rotor
fuel filter
Muffler
Catalytic Converter
valve cover gasket replaced

The Wrangler is still having issues and hope that someone might have a suggestion to point me in the right direction.

Thanks for the reply. I am not sure what you mean by "converter not unlocking". I just had the CAT replaced last night, So I don't think it is a CAT issue.
