Well I got my new penguin heat pump, installed it and all is working good. Thanks to all for the help. I tested the compressor motor with an ohm meter and I believe it checked out good.
After thinking about all this, I think the stop leak I put In a few years ago may have finally come back to haunt me. I had one leak and fixed it then I got another leak that I just couldn't find. So I tried the stop leak. It cured the leak. I don't think the compressor ran out of oil because I never saw any sign of oil, even around the leak I found and fixed. Oh well. Back in service until the next issue.
