Gas pedal drops while driving
 

2014 Honda Accord Sport

While driving, I will be maintaining a steady speed and the gas pedal will drop from under my foot. It's not a lot, but enough to cause my foot to fall off. Not to the floor. There is no noticeable change in acceleration or power. Surges or loss. Literally over in a second and can resume driving as normal. Any thoughts?? It is definitely very scary every time it happens. This has happened twice in the past two days.
