In what article in NEC, is the answer for "Distance required for 375' run from main to subpanel using 2 1/2" pvc, with 3/0 conductors?
 
Welcome to the forum. Can you reword your question? It makes no sense as asked.

there is no listed distance between pull boxes in the nec ( 100 ft =myth), with the exception of vertical conduit runs that require wire supports
 
In 375', is a pull box required. If so, How many? Where in NEC 2005 edition, can this answer be found?

There is no limit in horizontal runs, just no more than 360 deg of bend, see all of the 3xx.26 article sections.
