Thanks Jim, I finally figured it out about 4:00 AM this morning. I woke up and it was 44 Degrees and rather chilly so I turned on the heat. The unit cycled for a few minutes and shut off. I got up and turned it higher and it came right back on so this told me that the unit wasn't shutting down because of gas or electrical problem. I cranked the thermostat up to 80 and went back to bed. After running for 20 minutes and realizing that I was starting to swet I got up and turned it down. I guess I just wasn't turning it up high enough, DAHHHHH!
Thanks again for the input.
