99 1500 5.9l I have replaced coil, crank sensor, dis, button, and board inside dis. Also ign switch. Sometimes it will run for a day or two and then quit with no spark again. Please help!!!

What brand crank and cam sensors did you buy? Also check the ground wires from head to firewall and the two grounds to the left of the power steering pump. You should also try swapping the ASD relay with the horn relay.
