Wife was driving down the road jeep lost power for a few seconds the kept going. When she pulled into the driveway it died and would not restart. after and hour or so sitting restarted no problem.

There is a black fuel relay way up under the top left driver side dash that breaks its main wire solder connections on the circuit board under over-heat conditions. Resolder that relay. Starting fluid will show that you have lost fuel delivery under no start conditions. You can use the breather hose from the valve cover for this test.

No engine light on? Sounds to me like the bumpy road may be knocking something loose. It would help to know if you have fuel pressure when the problem arises.

The truck is probably stalling on rough roads because the fuel pump float is not staying on the surface of the gasoline in the tank. Therefore, it is taking on air and interrupting the flow of fuel temporarily. It may be sticking a little and operating too slowly.
The fuel pump is inside your gas tank but can be removed and replaced by you if you are skilled enough.

The only component I know of, that shuts a Jeep off while idling or driving 40mph down the road, is a bad crank sensor. Usually when it starts going bad, it will sporadically shut off, like yours does. Eventually, it will just die and the Jeep will not start at all. Have it tested and replaced, if necessary.

If the brake pedal goes hard right BEFORE the car dies, and not after, then you could have a problem INSIDE the brake power booster. try to verify this next time it dies at a stop, if you can safely pull the dead car off the road into a driveway (or try to make it stall in a bumpy parking lot) - then before you try to restart the car, open the hood, pull off the rubber hose where it's plugged into the brake power booster --> you SHOULD hear a big "Swoosh" of air being sucked into the booster because there's supposed to be a strong vacuum there even after the car stops running. if you get nothing there, your car is dying of an excessive vacuum leak through the brake booster.= bad booster.

Well, I would try to check the spark to make sure the ignition system is providing spark to the spark plugs. Then, I would check fuel pressure, to make sure that the injectors are getting enough pressure to provide gas to the cylinders, using a fuel pressure gauge on the rail.

Timing chain may have skipped a tooth or maybe fuel pump has failed.

could be fuel pump check fuel pressure when it dies

Ignition Control Module is bad. When the dielectric grease used to mount them gets hard,they overheat and cause you to shut down. Really easy to install(about 10 mins.). I had this happen on two Fords. If you let the engine sit and cool down,they will fire up and run till that part gets hot,then itll die on ya. Auto zone sells this part for around 35 bucks.

Run a scan tool to determine problem, if nothing found take the car to the nearest acura service center to check for any recall onthe car.
