1996 f250 5.8l wants to stall in stop and go traffic--bad gas?

It could be vacuum lines. Once your engine warms up it switches a circuit to something that has a leak. Check your vacuum hoses. It's a cheap fix if that's all it is. And, it's pretty common.

Thanks for the response!!, I'll get on it, this problem happened with no symptoms or warning and no check engine light triggered yet. I thought it was the other way around, if there was a vacuum leak it would have starting problems and not want to idle cold, Thank you again and I'll let you know what I find!! Thanks Bryan

I had a Toyota which did something like that. Only in my case, it would stall out if I stopped for a short while, such as to pick someone up or get gas, or got stuck in stop & go traffic. My problem was the carb emptying out, if I primed it manually (pop hood, etc), then I was good to go. Turns out that problem was a flaky fuel pump. Sigh.

could be contaminated fuel, anything heavier than fuel will settle to the l owest part of the tank which is exactly where the fuel pump siphon is locat ed, highway driving the fuel is getting sloshed around but once you come to a stop it settles and that's when the engine starts misfiring, it's winter time and chances are you got some contaminated fuel..
