Small Engines (Lawn Mowers, etc.): Husqvarna fuse blowing, husqvarna yth1542xp, amp fuse

Question
I have a four year old Husqvarna YTH1542XP.  After running smoothly for about an hour, it shut off in mid-mowing.  I didn't hit anything, no blade problems.  No turnover when turning the key.  Tried to jump off the battery with my truck, no luck.  The dealer said the battery went bad, so I bought and installed a new one - no change.  Checked the 20 Amp fuse near the ignition, and it was blown.  Replaced the fuse, cranked right up - but fuse blew again after about 5 minutes.  Tried another fuse, same thing - blew again after about 10 minutes.  Any ideas?  Thanks for your help.

Answer
 Hello Ben:

 Check the Entire Harrness for Bare Wires. Check the Bulbs (if any). Check the Charging System for Surges/Spikes in Voltage. The Charging System can Surge/Spike and this Blows the Fuse. Hope this Helps. Let me know what Happens, Please.

 Good Luck

 Respectfully
