Pipeline error: Formula Query Execution took too long

I found some posts similar to this regarding reports but none for Pipelines so here is my situation.  I've also run the Performance Analyzer, Performance Insights, and Performance Optimizer but not have provided any advice other than "optimize your query". 

When running pipelines, I get 3 outcomes:  Success without issue, Success with Heavy Traffic notifications, Failure due to the Formula Query Execution taking too long.

This happens on the exact same table, using the exact same pipeline (no differences between runs).

Success without issue happens on the weekends or middle of the night.

Heavy Traffic notifications seems to be hit or miss during the day on weekdays.

Failure due to Formula Query Execution happens during the weekdays during typical office hours.

Based on these scenerios, I am guessing it is a Quickbase "resource availability" issue????

The table is ~ 4000 records with 57 fields. 

Below is the Pipeline activity output for one of the failures.  Sometimes it makes it through nearly all records and then dies.  Other times it dies after the first few hundred.  This particular pipeline exports 20 fields but it also dies on similar pipelines for this table that export only 5 fields. 

The pipeline grabs all records in the table and shifts data between the 20 fields exported as part of this pipeline (data in fields 11-15 move to 16-20, fields 6-10 move to 11-15, fields 1-5 move to 6-10)
