98 Jeep gauges randomly failing

While driving in normal conidtions all gauges will return to zero and the airbag light will come on (sometimes I’ll get the check gauges warning light). Also the electric windows will not work. There are no error codes. After a short time everything returns to normal.

There is no change in performance or operations of the vehicle (radio works headlights work). Any ideas whats going on? There is 127,000 miles on it. Thanks,

It sounds like the power supply line to those areas needs to be checked, possibly for a bad connection. I suspect there is a single line causing this.
