Hello guys i recently bought a 07 HR AUTO

Everything seems fine pulls great what happens is after a pull or under load it stalls coming down from the rpms after relaxing the engine
so like i'd be going down the highway i'd do a puil 3rd gear lets say shift to 4th it goes but after you slow down boom no response from the engine you press the pedal revs go up but nothing moves for at least 1 or 2 minutes then goes back to normal.

Everything Stock except for
Mods:
HKS Headers
HKS Mufflers
Custom Titanium Exhaust
UPREV

TL;DR
Car stalls for at least a minute after a pull or under load after slowing down.

The way you're describing the problem is interesting. The engine is running and rpms go up and that's "stalling?"
How many miles? Top off the AT fluid. If that doesn't help have the transmission serviced.

111k Miles (180k) km

yeah, basically you can go up the rpms the tachometer goes up to about 5k and you hear this sorta downshift noise but no response to the wheels for like a minute then boom engine starts moving again you hear the belt and the wheels respond again runs fine as long as i dont do a tough pull or go above 150 kmh or put it under any sorta load ill film it the next time i take it out and do a pull i went to nissan dealership cheif of service guy came in with me i straight up did a pull with him and when the issue kicked in he said something along the lines of your driving it like a maniac your making the ecu go into fail safe mode (also overreving) which i thought to be a total bs cause ive seen people push it way worse previous owner didn't deal with it he claims it to be to do with a tune i retuned it (uprev) and even under some load it does it so that didn't click with me and its kinda driving me nuts hopefully tonight i get you a vid.

Tl;DR 111K Miles you put some load you slow down car limps you push throttle tachometer goes up nothing happens for at least a min then power again out of the blue

Regards, AceXx:
Touring? GT? If so, VDC may be kicking in. If VDC equipped, find the override switch & see if it helps. Tire mismatch or worn may contribute. Dash light up?

First thought is to agree with jhc. Check transmission fluid level. At 111k miles, AT fluid may be low or tired. Since your Z shuts down after hard driving conditions do some research on auto transmission overheating. Good luck & keep the forum informed.

Peace,

Here's some videos to further elaborate

That's a transmission issue. Find someone with an advanced code scan tool and see if you have transmission codes stored.

most likely what is stated here.
