Control Circuit fuse blowing

I have a 8210 pallet jack roughly 4 years old that will work for about 1/2 hour and then blows the 15amp glass fuse for FU3 marked control circuit fuse. I went over everything I can and don't see anything wrong. I even went so far as to put a 20amp fuse in its place and it does the same thing after 1/2 hour of use. Any ideas as to what I can look for?

Most harness issues were remedied with later model jacks. But what will help is knowing when the failure occurs. Example: While steering to one side or the other. The older issues were under the handle assy. where the harness wires rubbed through to the frame. The other harness to look at is the handle stem at the pivot point. Sometimes obvious and sometimes not. Intermittent fuse issues usually were harness failures.
