Weber 32/36 issues

My truck starts up great after a few pumps on the pedal. She drives great. She idles really good..... most of the time. Although sometimes when im at a full stop she will be idling great then the next minute the engine cuts off? This happens probably once a day and usually after the engine is pretty warm. I also noticed that this occurs more often in the heat, but the temp gauge shows its not overheating. Please help me figure out what is wrong. Do i need to add more air or gas to the mix?? is this even a problem with the carb or could it be something else? Thanks in advance

Make sure that this is not an ignition switch electrical part issue. Do the dash warning lights come on when this happens?

No i dont believe they do
