We had similar problems and please note that there is no such thing as AUTO scaling on standalone databases on Azure and since you are using Entity Framework, here are some suggestions below

1. If you are calling Web-API to fetch and transact with your database on Azure SQL, make sure on Azure portal you set the "ALLWAYS ON" option for the Web-API.

2. Then your client app should probably retry if it fails to connect in the first attempt.

3. If the database queries are resulting in timeouts due to volume of the data and the indexes not able to catch up with that, you will need to increase the time out of the command executions a bit and most importantly you will need to update the stats on the database and recompile all the objects in the database.
