How often does Lahaina Noon happen?
Lahaina Noon takes place twice a year, in late May and mid-July, before and after the summer solstice, but exact dates vary annually.

Where is the sub solar point?
The subsolar point is at the Tropic of Cancer in June, and at the Tropic of Capricorn in December. Midway between the solstices are two dates when the Sun shines directly on the equator, and we have a situation like our hypothetical one, where the Earth's axis is perpendicular to the ecliptic.

What would happen if the Earth was tilted 10 degrees?
If the Earth's tilt were at 10 degrees instead of 23.5 degrees, then the Sun path through the year would stay closer to the equator. On the map the angle between the ecliptic and the equator would simply be reduced to 10 degrees.
Is the Sun ever directly overhead anywhere in the United States justify your answer?
Answer: For continental U.S. the answer is never. Since the Earth's rotation axis is tilted 23.5 degrees with respect to its orbital motion around the Sun, one would have to be less than 23.5 degrees above or below the equator to have the Sun pass directly overhead (once per year).
