2017 NISSAN MAXIMA Fuelpropulsion System Problems

My car has been "losing power" while driving. While driving and pressing the gas pedal, the car will stop accelerating and kind of goes into an idle state. Highly dangerous! It happened the other day while I was attempting to enter traffic. It has been happening off and on for the last 2 weeks and has been happening more frequently, meaning several times a day. It seems to happen more often when the temperature outside is hot (90+ degrees). Also, with the last few times, after it happens and I regain power, the ABS light comes on and remains on until I shut off the engine.

I HAVE AN OBD READING OF P0171 P0174 P219B AFTER I CHANGED THE BATTERY ON IT.

THIS ISSUE IS INTERMITTENT, HAS BEEN CHECKED SEVERAL TIMES BY MY DEALER AND DOES NOT SHOW UP IN ANY ERRORS. THE CAR WILL STALL AT RANDOM TIMES. IT STARTED OUT MOSTLY WHEN I STOPPED ACCELERATING, EITHER WHEN STOPPED AT A LIGHT OR TURNING A CORNER. OCCASIONALLY WILL STALL WHILE DRIVING. USUALLY IT IS VERY BRIEF BUT OCCASIONALLY TAKES A FEW SECONDS TO RE ENGAGE. ONLY ONCE ON THE FREEWAY BUT PRIMARILY ON CITY STREETS. I AM REPORTING THIS TODAY BUT IT HAS BEEN HAPPENING INTERMITTENTLY SAVE I PURCHASED THE VEHICLE SINCE MAY 2018.
