This is exactly how my '98 TJ 2.5 started behaving prior to my
replacing the crank position sensor. Seems the wire between the
sensor itself and the plug on the other end came into contact with the
exhaust manifold and melted the insulation, causing a short.
Until I discovered this, I went absolutely crazy replacing things like
plugs, rotor, cap, throttle position sensor, etc.
Something to check out, at least.

Re: 99 TJ 2.5 Hesitation
I personally have never seen a Jeep engine that would run well for even
one year on 'platinum' plugs. As soon as they get the slightest wear it
seems, they start missing under load.
Others here have had good luck sometimes with them it would seem,
so.....

Hi Mike,
Ditto! I conclude Blush didn't try to match the AMC's heat range as
closely as Champion. The same thing could be said for a Champion in a
Volkswagen bug engine.
