could well be Crank position sensor failing or the ignition switch is breaking contact
Could also be worth checking the main power and earth points for corrosion

Replace the battery. Low volts caises very weird things to our Jeeps.

The first thing that comes to mind when you say you have to relieve fuel pressure is the gas cap. Is it the correct one for your rig?
