take a spare spark plug and when it will not restart, take the spare spark plug, attach it to the spark plug wire, and with the plug grounded, see if it has spark. No spark, the coil is bad. If it has spark, check the fuel tank hose for debris and be sure the fuel tank is venting, by loosing the fuel cap.

Ive pulled the plug out and checked the spark it's real good several times right after it does it I've also drained yhe tank blew it out and and the filter inside the tank through the bottom spicket all clean when I let the fuel drain frome the tank through fuel line doesn't seem like alot coming out and the line is clean blew it all out with air hose could I be tightning the fuel cap to tight so it can't breath maybe

It has to vent, or it will draw a vacuum. Give it a try.
