A corroded body ground can act like that.... I would run a booster
cable from the battery negative to a metal contact on the body to see if
it then starts.

Up here in the rust/salt belt those mesh body ground cables rot out easy
then the starter sucks all the juice and doesn't leave enough power to
jump the bad body connection.

Mike,

Are there any problems that cannot be caused by a bad body ground?

How about this one?

Just bought a Pickup (not a Jeep - mine's off the road for major
restoration). The wipers turn off whenever they want. Last night when I was
driving it home, the engine sputtered for just a second, when I turned on
the high beams. Didn't do it every time I turned them on, but at least five
times.
