so i took out the zilla the other and i think it wasn't my day

....first it started leaking water out of the wheep hole wich is because the housing around the waterpump shaft is broke a bit....then i took it down the rode for a sec and i lost spark...pushed it back and kicked it once and it fired right up........took it back down the road and it quit again.....pushed it back and then it wouldn't start.....in what order would it be smartest for me to find out why i don't have spark......any imformation would be great...i already checked all my connections they are solid....
thnx
