Intermittent Engine tick and loss of power

04 4.0v6 259k on the clock. Been having an intermittent tick noise on the front passenger side of the engine. It does get worse with higher RPM and I am loosing power but I don't lose power every time I drive. I've seen a few things from something in the valve train to a a bad pulley but nothing mentions loss of power. Anyone have any ideas? I'll try to link a video if I can.

 

Video would be best, or at least a recording of the sound. If not then a VERY detailed description of what you hear and where. Any codes thrown?

Heres a link to my drive folder. The one at night was last night with the faint ticking, the other is from this morning and the ticking is gone but its defiantly a pully bearing or something. I am going to try and see if its still present with the serpentine belt off. I think I may have two issues though, the noise and the loss of power because the loss of power is also intermittent.
