A number of people in the link report the same problem on the Jeep Forum and there are a number of fixes.
I also found this for you.
The problem seems to be a short in one of the rear dome lights, which seems to be affecting two fuse circuits
. The temporary solution was to remove one fuse and replace another (blown), and remove the bulb from the bad dome light. I had to remove "fuze#5-15 amps-Interior Lighting", this stopped the clicking noise, I replaced blown fuze#8-15 amp-Overhead Console, keyless Entry ..." This fuse also seems to effect the alarm system (contrary to the documentation), and I think that was what was killing the engine. The problem existed before fuse#8 blew. Removing fuse#5 may have solved the problem, but the other fuse blew while I was testing the dome lights, and the jeep will not start without it.
Found lots of wires bare or broken in all the door wiring harnesses ( in rubber
boot that goes to the door)I first checked both fuse 5 and 8 but both o.k. After fixing the broken wires found fuse 8 had blown. Replaced that and all is well again. Thanks for the advise got me looking in the right direction.
. Fuse box located in passenger side door jam
...check #8 fuse if its not blown check others...if it is blown, check your radio, and interior lights for good ground
Clicking noise under passenger dash Jeep just shuts down
