this 1991 60hp johnson i noticed that it didnt spark at all on timing light 1 time. than the next time they all lit up..???? motor starts for few seconds sometimes and dies right away.... 3 spark plugs..... is this possible to have spark on all 3 plugs sometimes and sometimes no spark on any ????? each sparkplug has its own coil
 
"Remove the black/yellow wire

"Remove the black/yellow wire (kill circuit) from the powerpack or from the back of the ignition switch.

If you now have spark, the usual cause of the problem is intermitently shorted ignition switch."
