What causes my van to idle then kick into gear when I try to go & sometimes die when I'm stopped?

This only happens when my van is at a 1/4 tank of gas. I'll apply the gas to go and it'll rev but not go, then it kicks and starts going, sometimes it takes a few seconds for it to completely start going without shuddering. And when I stop, it's****** and shakes, and sometimes dies, but it always starts right back up. And it only happens at a 1/4 tank of gas.
