Hi, @biengineer ;

1. Please check whether there existing any step in Power Query consuming too much CPU or memory. And try to use Table.Buffer to improve the data load performance.

2. Use DAX studio/ Performance Analyzer to check out which's the most time-consuming:

Follow this blog to install the dax studio,then connect the opened pbix file in dax studio
