I am having a problem with my van stalling every time I come to a stop sign. Starts in the morning fine, but seems to occur when it warms up. After it quits, it starts up just fine and runs like a top as long as you are giving it gas. When I let off the gas, it starts hunting for idle. I have no engine light coming on. Where should I start to diagnose this?

Thanks in advance for your help!
