Sounds like the vacuum is dropping off & its not lifting the slide,
How long do you have to wait before it starts back up after it pukes & dies?
Were you real careful to make sure the slide & where the slide runs in the carb were clean & dry, as in no fingerprints, no oil at all?
Was it doing this before you cleaned the carb?
How old was the old gas? What did it look like in the carb bowl?
Have you tried the choke? Have you had to use prime to get gas to fill the bowl back up?
