I replaced the starter. No change. I then replaced the solenoid. At first there was no change, but then it started working and fired right up. Mowed about an hour, shut it down to take a break. When I went to continue mowing, It quit working again. Haven't been able to start it since. Fortunately I have another mower and was able to complete mowing with it. I can rotate the engine by hand with now problem. I'm thinking it might be the ignition switch. I'll try swapping with the other mower, also a Husqvarna, to see if that helps.
