Hello.

I suspect that when the database instance has low specs and heavy queries are executed, the CPU usage rate increases, leading to timeout errors.  
Is your database instance using RDS?  
If you are using RDS, you can use a feature called Performance Insights, so enable it and try to find queries that are taking a long time to process.

There may be problems other than the database, so I recommend checking the application log and checking for errors.
