2000 Wrangler Stalling Condition

I am having a difficult time solving a problem. My jeep stalls at idle only when it is very hot out and after the engine is warmed up. This seems to happen every year in the summer. I have a 2000 Wrangler 4.0 manual. At idle the car will be runnig fine then the idle will drop suddenly to roughly 500rpm and the engine will start running really rough and then die. I try and modulate the throttle and sometimes I can get it going but many times I cannot. It restrarts right away. When it stalls all the dash lights go out but when I turn the key on/off they all come back on and the car starts.

I changed the TPS and cleaned the bypass. Also checked the following grounds - engine to chassis, battery to chassis and chassis to hood - they looked good but I cleaned them up. New fuel pump went in last summer.

Any help would be appreciated.
