Original post said AC was disconnected & no belt. Most likely cause is alternator belt slipping under load. That version has the York compressor & bracket above the alternator, makng checkng & servicing the alternator belt more difficult. The belt may seem OK but be slipping when first started or engine is revved. You'd need to remove that belt to verify if the waterpump or alternator is seizing/dragging. Also, The wear surface of the belt could be hardened/glazed. Otherwise, try to tighten it.
