What would make jquery stop working?
<p>Not able to show code because it is way too long but here is scenario:</p>

<ol>
<li>jquery is loaded at top of page</li>
<li>jquery code works normally in middle of page.</li>
<li>at some point jquery stops responding to event handlers and selections.</li>
<li>inserting link to load jquery again before non-functioning code re-enables it.</li>
</ol>

<p>So - what would cause jquery to stop working?</p>
