Hard Starting After Warmed Up.....Arrrg

Yep, it takes time to get it right on ignition. Some Mopar distributors are much easier to adjust than others. The first link I posted is the older/harder style.

If the rotor tower, where you press the rotor on is bronze in color, that's the easier type. Cast colored, hard style.

I hope your wife gets better. I deal with a family member that's been "hampered" from an injury for over 15 years. It's a struggle, time consumer, draining, etc but I refuse to place them in a home when I can help out. Hope the best outcome for you.
