Hi, add a new ground wire and ground it to the MOTOR very important. Just take any ground wire you have and ground it to the motor.. Once that is done check agian for spark. If still no spark. Make sure the cdi box is pluged in all the way and coil leads... There is only a few things that make it stop sparking.. Stator pick up coil ground wire cdi box then coil...
Check the leads and coils.. also cables from the coils to the ignition system..

check the oil level in the differential. If run a long time low on oil it may have damaged gears and bearings. Look for leaks past seals and cover gasket.

Unscrew your gas cap when it is dying to see if it is plugged up not letting any air in. It sounds like it is creating a vaccuum in the tank and by switching lines you relieve it temporarily. Good luck hope this helps...
