1987 Bronco 5.8L Holley 4 barrel

Does anyone have any ideas why it suddenly decides to drop idle and die for no apparent reason at all? I had the carb adjusted, gas was pouring into the carb, I could see it, it ran okay for a couple of days, now it does it again. Think it needs to be rebuilt?

you need to pull your carb and take both float tanks off and adjust the needle valves and replace the orings on them.
then adjust the floats dry and make sure they are paralell with the bottom of the tank.
they also have a site hole on the side of it so you can adjust them while it is running just keep the gas at the bottom of the hole.sounds like it letting to much gas into the float tank and flooding you out.when the idle drops again look in the top of the carb and see if you see gas dripping,even sometimes when you first cut the engine off
good luck

If you keep having a chronic problem even after you mess with the carb, I would say you have a fuel filter problem, and maybe a rust/dirt problem in the gas tank. It only takes one little piece of dirt to get stuck under the needle of the float to make it flood.
