NHTSA Complaint #11588821 — 2016 NISSAN ALTIMA

I was driving on the interstate highway when I realize that when I was trying to accelerate, the car was not starting to move forward anymore was not able to drive at proper speed on freeway . prior to that, I realize my RPMs was going up and down Had to pull over on freeway shut my car off and let car cool down waited about 10 minutes with off and then restarted it and continue to go seem to be fine at that point but has happened a couple times to me already, driving at normal speed and then it seems like when it’s getting hotter that I would gradually wouldn’t be able to move at normal speed as I needed to be on the freeway. RPMs would eventually start jumping up a down again I end up bringing my car to a Garage have transmission flushed and change screen filter, and oil cool filter still same result. It seems to feel very unsafe when driving on freeway!!!!
