I've dealt with this on several cars before and it always turns out to be a vacuum leak. The car I went through this on, would shut off when it was cold. I could start it and it would turn over and then immediately sputter and shut off. I had to turn it over and then hold the gas down till it warmed up. Once it was warm, all was well. Occasionally as it got worse, I would get a miss here and there but nothing crazy, before I replaced the hose. On the last car, I spent about $800 on parts I thought it was. Eventually I was so pissed I just tore it down to the head, and wouldn't you know it, a hose from the oil separator to the dipstick tube had melted from the engine heat. So vacuum leaks can be a PITA to find sometimes, even with a can of Carb spray, but they sure are cheap to fix. The hose could be cracked so when the engine is cold, the crack is open more. As the engine heats and VAC hose rises in temp, it may have enough life left to seal it up bit, which is why you aren't getting a misfire when your warm. I would start checking hoses. Bend them as well, if they feel dry and show cracks when you bend them, replace them.</blockquote>
