shutoff

Need some input to assuage my fears about a fuel leak after a recent air filter install. On my last weekend ride, I had just finished filling up my tank about 3/4 of the way and took off to head home. Exactly 1 mile later or about 3-4 minutes after my fill-up, the bike power suddenly cut out...

To eliminate excessive draw on the battery, can you simply turn off the DDA on the dash and/or unplug the red module at the undertail. Thanks in advance.
