Let me explain autopause „when stopped“:

First - I assume, you don‘t use a speedsensor. Then speed signal is built from GPS. Means: you need to have a sat fix (good and steady GPS signal). Without GPS autopause will not work.
The header of your posting says: GPS loss of signal, but you don‘t mention it in your text.

In general: watch the speed value on your Edge! If there is no speed, autopause will not end.

Thank you for the reply. Correct, i don't use a speed sensor.  I am assuming that the gps is losing its connections since this what tells the  device "you are stopped or your are moving".  So it appears that autopause goes on because it lost sattelite connectivity. I read one other post that decribes this issue but i did not see any responses or solutions. This garmin is a replacement for a garmin 800 which worked pretty flawlessly so i'm wondering if this is just a lemon. 

Autopause starts during ride and freezes the 1040

I sent the unit back thinking it was just faulty. got a new one and the same thing happened.at 2 seemingly random times, autopause kicked on and would not resume. i cannot believe i am the only person to have this problem with this device.could having both a hrm and cadence sensor cause the satellite signal to drop out?

Your problem is probably due to GPS reception, and you should concentrate on this first.
There is a data field that shows the GPS quality. Put it on your screen and observe it.
There are several combinations for the reception of the positioning system. Try the different possibilities (GPS only, GPS +Galileo etc...)
Once you have consistently good satellite reception, the autopause problems will also disappear.
The HR and Cadence sensor has nothing to do with GPS.

Thanks both for the suggestions.  I will give both of these a try and see what happens.

One other piece of information. My husband has not had the drop outs when he has ridden with this. The 2 differences are that i have bluetooth shifting and a cadence sensor. Is it possible that the bluetooth shifting could be something that would interfere with GPS signal?

I'm Having the same problem as you.

Loss off GPS and Autopause enabled even when riding.

It's odd that several users seem to be experiencing similar problems at the moment. Like most others, I've never had any problems with GPS signal. Quite the reverse, in fact; I've been using Garmin devices for 15 years, and whereas old models like the Edge 705 could take forever to acquire a good fix the 1040 is basically instant, and gets a usable signal even indoors. Nonetheless, and others have said, check that you have a good signal before you start an activity, as others have said. 

The manual says this:

Improving GPS Satellite Reception

• Frequently sync the device to your Garmin account:

◦ Connect your device to a computer using the USB cable and the Garmin Express application.

◦ Sync your device to the Garmin Connect app using your Bluetooth enabled phone.

◦ Connect your device to your Garmin account using a Wi‑Fi wireless network.

While connected to your Garmin account, the device downloads several days of satellite data, allowing it to quickly locate satellite signals.

• Take your device outside to an open area away from tall buildings and trees.

• Remain stationary for a few minutes

It's worth following all that. Older devices used to have the facility to clear the satellite cache, but that doesn't appear to be the case with the 1040, so nothing to be done there. I'd second mcinner1's advice about trying different satellite settings - there was an issue with the old 705 once during which it would regularly lose the signal if GLONASS was enabled (if in doubt, blame the Russians! ). It's not impossible that it's something like that.
