-- OEM brand fuel pump Not really needed, oem tends to have a limp home mode, in the 30yrs of owning/restoring/wheeling Toys(aover 40 rigs between myself and friends), have yet to see one fail. If concerned due to age, just replace the current one w/a new oem one.
-- Alternator Normally triggers the "Charge" light, and can also be tested before leaving
-- Tire repair kit
-- Distributor Another rare if ever OEM failure
-- Hoses and wire
-- Fuses and Fusible links
-- Ignition coil Not a bad idea, small in size, but another item rare to failure
-- Starter motor and solenoid Another part that tends to let you know it is starting to go, trail side/parking lot fix is to forcefull tap it a few times with a hammer, only really need to carry extra set of contacts
-- Wheel bearings Not needed, if they fail on the trail they were in bad condition and you should have been aware of it on the street
One of the best ways to avoid back country issues with most of the items you have listed, is to use oem parts over parts stores, or have the oem parts rebuilt, maintain your rig, and do a once over(pre-flight check) before heading out.
Would add,
Basic tool set and a set of long sockets
Hi-lift jack
used set of drive belts, spark plug wires, cap/rotor, a couple of plugs, fan clutch
Basic tool set and a set of long sockets
a spare hub, yet another rare oem failure
spare engine mound or chain
duct tape, plenty of uses, can even be used to plug tire(roll up sticky side out)
heavy duty zip ties
electric tape and 12 gauge wire, cheap multi-meter, test light/circuit tester
1-2qts of gear oil, 2 gal. of anti-freeze and rad leak stop, a couple of quarts of oil

steering linkage components,
Rear driveline.
starting fluid
If running a front locker, spare birfs or a cv
Main relays and fuses
spare bolts for any of the trail side repairs you may do, real easy to lose bolts in the dirt.
If going to be out alone, something that should avoided,
dual battery set-up
Backpacking gear that will allow you to hike your way out safely for the time of year you are out and the distance you would have to travel.
emergency beacon or
gps/sat phone, as all the repair parts in the world are useless if you can't make the repairs due to injury.
