2006 Jeep Wrangler keeps dying - electrical issue?

A few weeks after purchase, this Jeep just died while driving. None of the gauges would work, wouldn't crank, etc. Had PCM replaced and it worked fine for a bit. Then suddenly, it strands us in the middle of nowhere in the Bighorn Mountains of WY...and it acted just the same - died while driving, no gauges. Towed it home and took it to the shop that replaced the PCM. They said it was a bad 20a female mini fuse (Fuse 9 in the engine block fuse compartment). They replaced that and it ran fine. Then, driving across town, it died three more times each time we hit bumps in the road...and acted just like it did when the PCM failed. Each time it died, we replaced the female mini fuse (fuse 9) and we got home. In the driveway, each time my husband tried to start it, it would not turn over and the same fuse would blow. He played with some wires and found a bare starter wire, which he insulated. He also fixed a couple of other wire splices in the doors that had been done poorly by a previous owner. No PCM error codes. Drove it today and it was just fine. Just don't want to get stranded in the middle of nowhere again. Will definitely carry fuses...but does anyone have any ideas?
