Insert into table from view is realy slow

Hi All

There is a big view which we use for fill a temp Table.
There is a job which run every minute and generally it takes 30s.
One week ago, something happens and the running time grown up 5m.
I tried to figure out why, but I have no idea.

If I select all the data from the view It takes 20s and the insert part takes more than 4m

Thank you for any ideas

without any ddl, sample data, etc... we won't be able to help you? How many rows are being returned in the view? What does the execution plan look like? without any of this, we'd be guessing
