Hey man, don't worry, you have killer bass..

I love mine.
I think both issues can be easy to get rid off.
First - the cutting out - maybe it is a problem with pickup - the replacement for the same one is for like $70, no that big deal.

Or it can be just loose wire in the electronics that is easy to be resoldered by a technician.
As for the tuning slipage - this could be the bad string grip on the tuning post - try to change strings set.
Or at the worse case the tuner change might be needed. Again, no big deal.
So bring it to a tech, these are minor issues.
Enjoy your great bass.
