Carburetor flooding sounds like. Float needle gets stuck open with trash in the fuel line. Mine used to do that until I rebuilt the fuel system end to end.

Check the inside of your distributor cap, rotor and points. If they look good and your points aren't worn or corroded, check the gap on the points and reset if needed. Put it all back together and see if it starts. If it doesn't, pull a spark plug and check for spark. If no spark than its either the coil or condenser.

Any resolution on this? If you let ethanol fuel sit in the Jeep it’s hydroscopic (absorbs water) so it can ruin a fuel system in short time. Sounds like you could have a fuel issue or ignition.
