If you've had it in for repair that many times, it sounds like the problem isn't the wiring, but either the pot or the pickup itself. Whichever it is, you have plenty of options available to you when it comes to replacements;
1. You could keep the sound you already have by getting a set of replacement pickups and pots. The Stratosphere has pickup sets and pickup+pots sets from a couple of 2021 Aerodynes.

2. You could sift through several Precision bass pickup demos on YouTube, zero in on a brand and model you really dig and go from there.
3. You could start by replacing the entire wiring harness. If the problem persists, then you'll know for sure it's a problem with the pickup. On a side note, if it were mine, I'd get something that lets me switch between parallel and series modes to get even more capability out of the 'Dyne.
Personally, if I really like the feel and looks of a bass, a faulty pickup or pot is not enough of an issue to get rid of the entire instrument. That sounds kinda like a
"throwing the baby out with the bathwater" sitch to me.
