note1      myprocess       8/4/2016      
note1      myprocess                            8/5/2016


I want to group the two records on Note and Process and return a date difference between Start and Stop

Returned

Note               Process            DateTimeDiff

Rows, not records. Any chance to change your data loading?

Otherwise it is a simple GROUP BY:

SELECT  Note, 
        Process, 
        Min(Start), 
        Max(Stop), 
        DATEDIFF(DAY,Min(Start), Max(Stop))
FROM yourTable
GROUP BY Note, Process;
