I'm guessing you want to print the lines between the first and second occurrences of the given string:

read_file = open ('C:\Users\Mahya\Desktop\\automate\Autosupports\\at1.txt','r')
content = read_file.readlines()
found = False
for line in content:
    if line.contains('===== BOOT TIME STATS ====='):
        if found:
            break # Exit the for loop when finding the string for the second time
        found = True
    if found:
        print line

Without testing:

read_file = open ('C:\Users\Mahya\Desktop\\automate\Autosupports\\at1.txt','r')
content = read_file.readlines()
i_found_the_block = False
for line in content:
    if "===== BOOT TIME STATS =====" in line:
       print ("found")
       i_found_the_block = True
    if i_found_the_block:
       print line
