Other queries on /page/* broken

After fighting pagination for a few days, it works, but presented a new, strange problem.

On /page/* of a custom post type, all other queries are broken.
The page itself has 3 queries (schedule, news items (pagination), highlighted item).

I isolate each query:

$temp = $wp_query;
$wp_query= null;
$wp_query = new WP_Query();

/loop/

<?php $wp_query = null; $wp_query = $temp;?>
<?php wp_reset_postdata(); ?>
<?php wp_reset_query(); ?>

Any thoughts?
Much obliged!
