I have a 2014 Ram 2500 5.7L with 4.10 gears and 150k miles. At the beginning of last summer I started getting a loss of engine power after sitting in heavy traffic for an hour or more with ambient temperature at or above 90 degrees. The condition doesn't feel like a dead miss but rather like the engine is de rated. When I hit the throttle and hold it at let's say 1/4 there is a noticeable lack of power. If I stay on it after a few seconds it comes to life and feels normal. I have tried manually shifting and there is no change. Once the condition comes in it will stay that way for several days of driving with no traffic before it clears up. I have disconnected the battery and it seems to make a big difference but the next time I am stuck in traffic it returns again. I replaced the plugs at 100k and perform all required maintenance. There are no codes and it does not happen in cold weather (no issues in the NE winter). I was thinking maybe a weak coil pack but I don't have any misfire codes to support that. Any ideas on what to check?
Thanks in advance
