Cache enabled Error loaded _before_ unserialize()

Fatal error: View::render() [<a href='view.render'>view.render</a>]: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition &quot;FeatureVehicleBlockController&quot; of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide a __autoload() function to load the class definition in

I have seen this error a couple times, but have not found a solution I can't enable the cache without throwing this error.

I think it might be something in the block code. The block is pretty basic I'll post the view & controller to see if someone can help, I can't enable cache until I resolve this and the site is super slow.

controller.php
<?php
   class FeatureVehicleBlockController extends BlockController {
      // caching for 5.4.1
      protected $btCacheBlockRecord = true;
      protected $btCacheBlockOutput = true;
      protected $btCacheBlockOutputOnPost = true;
      protected $btCacheBlockOutputForRegisteredUsers = true;
      protected $btCacheBlockOutputLifetime = 300;
      protected $btDescription = "A simple feature vehicle block.";
      protected $btName  = "Feature Vehicle";
      protected $btTable = 'btFeatureVehicle';
      protected $btInterfaceWidth = "400";
      protected $btInterfaceHeight = "300";
      function on_page_view() {
         Loader::model('vehicle', 'idealer');
