Loud pop, engine shut off and will not restart

I was accelerating after stoplight heard a loud pop almost like I ran over a balloon engine immediately shut off. I pulled to the side of the road checked engine, no fluids coming out, no smoke from engine or tailpipe, truck wont restart. It cranks over like normal, but wont restart. It's getting spark, getting fuel, I can hear the fuel pump engage when I turn the key on, changed ignition coils, and wires, has newer starter, radiator, and battery. Please help
