That is interesting considering there is dirt and contaminants in the fuel we purchase. All filters, if they are doing their job, get dirty. Regardless, since there is no check engine light, I feel the vehicle is running properly as far as sensors, computer controlled devices. Since the problem is happening at a high speed only, I would recommend checking fuel pump pressure to make sure it is within the manufacturer's specs. If it is low, it could cause this issue.
