There's very little actual load on the engine when it's in neutral so many ignition problems don't show up in neutral. To me that sounds like an ignition issue. I'd take a look at the plugs and wires. It could also be a lack of fuel. There's really no way to know for certain without scanning but plugs and wires are always a safe bet when you're having problems like this.
