Default 99 grang cherokee running issue

im thinking about getting this jeep off my dad. its a 4.0 auto it runs fine for a bit then it just doesn't want to run unless you rev it and stay on the gas. has no codes that pop up except rear o2 sencer cause the cats been deleted.we have replaced the coil pack and fuel pressure is good. i know it got to be electrical just dont know what. any suggestions?
