Wiring problems of the 2014 Jeep Wrangler

While driving moderate speed on a rural rd (est miles 115k), all red & yellow lights came on, "no bus" light came on which is not listed in the ops manual, windshield wipers came on, rpm gauge went to zero, fuel gauge went to empty, engine light flashing and engine running rough to possible stall. Within a period of time 10 min or so everything came back to normal and Jeep ran ok. This has happen to my wife who is a rural mail carrier on many occasions. In fact in 1 week it happened every day and it has happened many times over a long period. Jeep service folks don't know what is causing the problem as the codes do not pin point the problem. They "think" possibility it could be pwr fuse box, main computer or fwd instrument panel ea at a cost of over $1000 to replace. Service folks want t Jeep brought to them with lights on, gauges zero, engine light flashing but it's an intermittent problem and they are 30 miles or more away depending where the problem happens. Service folks have had the Jeep for a total of 3 days in Jan & Feb and drove it over 150 mile and the problem never appeared. In Feb 2015 while driving (24,171 miles) the engine light came "on" and Jeep stalled in the middle of the road. It was restarted and driven so Jeep was then taken to dealer and they found that a fault code said "wiring does not have enough slack between sensor & wiring causing poor connection". Replaced cam sensor & wiring. Fault cleared. Have photos of dash with "all lights and gauges showing zero and no bus light on and wipers going back and forth. I'll send if you need them but it all lights and gauges which are depicted in the ops manual. This possible engine stalling while driving and possible electrical fire is a safety issue. This problem has occurred over many months throughout 2018.
