That sounds like it may be a server configuration issue. What web server are you using? For Apache, you should have a single redirect in there that routes port 80 to port 443. If your server is listening to BOTH ports, you might see this sort of flip-flop behaviour.
Have you changed things in LocalSettings.php? If not, and your server is configured properly for HTTPS, then it should not flip to plain HTTP.
