Truck was running smooth than it started cuttering like it was losing gas. I pulled over and it stopped on me.

I'd just filled up on gas and the spark plugs and wires were changed only 2 days before.I checked the fuel filter and that was also okay. The truck was running perfect although it was burning alot of gas. Then out of nowhere it started cuttering as if itwas running out of gas. I pulled over and then it stopped. I can't get it to turn over and the spark plugs seem to not be getting any fire. Please help.
