fuel pump? what fuel pressure?

I had problems on the trail rzr would sputter and die after working hard going up a mountain trail after it was good and hot if it sat for a bit it would fire up and idle even rev but if u started working it it would sputter again and die when it died u could turn the key on and hear the fuel pump kinda sputter like it was having trouble and it wouldn’t start if u let it sit and turned the key on the pump would hum like normal and start

LONG STORY SHORT IM PRETTY SURE I NEED A FUEL PUMP

ALL I COULD FIND IS THAT ITS SUPPOSED TO BE 43.5PSI +OR- 2PSI NOT SURE IF THAT IS AT FULL THROTTLE OR JUST IDLE?

I TESTED FUEL PRESSURE AT IDLE IT SITS STEADY AT 42 PSI WHEN I STARTED DRIVING IT IT DROPS TO 36PSI AT WOT
AFTER IT GOT HOT THE PRESSURE WOULD DROP TO 34PSI WOT

I couldn’t get it to duplicate what it was doing up in the mountains I knew it wouldn’t cant work it like I was in the mountains especially in my neighborhood…

im pretty sure im gonna buy a pump either way I just want a little confirmation before I spend 300$ I really don’t want to have this problem again I had to take it down the mountain on the road and wait for my buddy to go back up the trail and go get the truck to get me…

thanks for any help
