Yeah I have the same problem also. I had my alarm installed by a reputable shop in my old state. The problem is that they have the autostart hooked up to a voltage sensor. When it is cold outside, it takes a little more cranking to get the engine started. When you push the button to start the car, it addresses the connection, cranks the engine, but not enough to actually turn it over. The result, if you didnt notice, a dead battery because your stereo and lights come on. What you need to do is have it connected to the tach sensor. I was told that mine didnt have a strong enough signal to make it tach sensed,(whatever that means). It is supposed to be real easy to fix in my car, the connection is right under the dash.
