Landing gear issues

hi all we have 2010 28 ft cougar.
Bought it last year and first time in October when were leaving the landing gear fuse poppes 30 amp
So I didn't do anything over rhe winter as when werw home i tried and seemed ok.
We took it on three week trip and it pops super easy
I just charged the battery to make sure it was topped off here at home and it popped again
Any help would be greatly appreciated
