Ok a new update. After checking it out today, when I started it the first time without a load and it ran about 45 seconds and died and threw the code 3-27 again. I started it right back up and put it under a load right off and it ran fine. after about 20 minutes I turned the AC off and it ran fine. So what I am seeing is it runs fine under a load but dies without a load. Now I am scratching my head on this one !!!
