Why do I have loss of power

Hello, not sure if you have the 2.3L 4 cylinder, the 2.9L V6, the 3.0L V6 or 4.0L V6 engine. Any way you look at it, diagnostic testing would be required. There's no guesses here. Since the problem appears to be acute, it shouldn't be too hard to figure out. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
