h All maintenance is up to date. It is a automatic.

This problem started about a year ago. It would loose power once every three months, then once a month, once a week, now every day. I drive four hours every day. Sometimes for the first hour, or maybe the second hour,or maybe the third hour i loose more than half of the engines power until the engine gets to 3300 rpm when i get full power back. When it shifts i have to wait till the rpms get to 3300 before i have any power. There are no engine codes. Usually during the four hours of driving the engine will run perfect for one or two hours but not all four.
