Sounds like it's starving for fuel. Not certain about your system but there
should be a check valve in the fuel pump or carb. If it leaks the fuel will
drain back into the tank and cause this (at least on the 305V8 it does).
The old Rochester 4M4 Quadrajet had a check valve as part of the fuel filter
in the carb. Had the wrong one in there (no checkvalve) and it dang near
drove me nuts.

Re: Nagging issue
That usually is caused either by the gas filter being in upside down or
a pinhole leak in the gas line on the suction side of the pump.
Both of these let gas back into the tank when it sits.
The gas filter has two outlets, the center one goes to the carb and the
'top' one goes to the return line. If the return line isn't at the top,
gas will syphon back to the tank when it sits.
No matter that you don't really know what Jeep you own, all the 258's
act that way.
