2020 Chevrolet Silverado 1500 fuel system problems

I was stopped n the drive thru at in-n-out with my foot on the brake and the eco system had turned off the motor. It spontaneously turned back on without me lifting my foot off of the brake and the transmission engaged and the truck launched forward approximately 12-18 inches. This is the second time this has happened to me. It also happened one night about 2 months ago. This could have been very dangerous, I could have hit someone or their car or I could have even received whiplash myself.

The check engine warning light was illuminated. The vehicle was taken back to the residence. The contact used a diagnostic tool to determine that the vapor canister purge pump needed to be replaced.
