滑块太快了

Question

我的网站上有一个滑块，滑块几乎完美无缺。发生的事情是滑块移动得太快一段时间后移动太快后滑动10秒滑块恢复正常

这是我的代码：

<section id="slider" class="container-slider large-12 column">
    <ul class="slider-wrapper">
    <li class="current-slide"><a href="historia.html">
      <img src="img/slide-photo.png" alt="slide 1" title="" alt="" class="">

      <div class="slider-icon">
        <img src="img/cat-photo.png" class="icon-slider" alt="">
      </div>
      <div class="caption">
        <h2 class="slider-title">Cavalo Lusitano</h2>
        <p>O Cavalo Lusitano é procurado como montada de desporto e de lazer e como reprodutor pelas suas raras qualidade de caráter e antiguidade genética, continuando a ser o cavalo por excelência para a Arte Equestre e para o Toureiro.</p>
      </div>
    </a></li>

    <li>
      <img src="img/test2.jpg" title="" alt="">

      <div class="slider-icon">
        <img src="img/cat-photo.png" class="icon-slider" alt="">
      </div>
      <div class="caption">
        <h2 class="slider-title">Cavalo Lusitano</h2>
        <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Illo iusto placeat aliquid tempore harum, similique!</p>
      </div>
    </li>

    <li>
      <img src="img/test1.jpg" title="" alt="">

      <div class="slider-icon">
        <img src="img/cat-photo.png" class="icon-slider" alt="">
      </div>
      <div class="caption">
        <h2 class="slider-title">Cavalo Lusitano</h2>
        <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Dignissimos dicta laudantium voluptatem minima! Dolorum tempore dolores excepturi omnis provident. Commodi quis aperiam maiores, dolore a perferendis!</p>
      </div>
    </li>

    </ul>

    <ul id="buttons-slider" class="buttons-slider"></ul>
  </section>

JS：

jQuery(function () {
var currentIndex = 0,
    lightboxLis = jQuery(".light-box li");

var list = [];

jQuery('.thumbnail li').click(function () {

    lightboxLis.eq(currentIndex).show();

    jQuery('.buttons').show();

    jQuery('.container-lightbox').css('height', '100%');

});
 if(lightboxLis.length <= 7){
 for(i=0; i<lightboxLis.length; i++){
  jQuery('<li title="'+i+'"></li>').appendTo('.list');
};
}
else{
for(a=0; a < 5; a++){
jQuery('<li class="esconder"></li>').appendTo('.list');
}
}

var currentLi = jQuery('.list li').attr('title');

if(currentLi == lightboxLis.eq(currentIndex)) {
    jQuery('.list li').addClass('active');
} else {
    jQuery('.list li').removeClass('active');
}

jQuery('.list li').click(function(){
    var current = jQuery(this).attr('title');

    lightboxLis.hide();
    lightboxLis.eq(current).show();
});


jQuery('.next').click(function() {
    currentIndex++;
    if (currentIndex == lightboxLis.length) {
        currentIndex = 0;
    }

    lightboxLis.hide();
    lightboxLis.eq(currentIndex).show();
    console.log(lightboxLis.eq(currentIndex));       
});

jQuery('.prev').click(function() {
    currentIndex--;
    if (currentIndex < 0) {
        currentIndex = lightboxLis.length - 1;
    }

    lightboxLis.hide();
    lightboxLis.eq(currentIndex).show();        
});

 jQuery('.close').click(function() {
  lightboxLis.hide();
  jQuery('.buttons').hide();
  jQuery('.container-lightbox').css('height', '0');
 });
});
