Default fuel pump question

So i have been messing around with my nitrous trying to get it figured out its been being a pain and can't get it dialed in. It goes rich and is popping and whatnot. So I finally got it close and i was comming back into town and my fuel pump quit working. This is not the first time it has acted up before when just driving around. Well it was the relay the first time put a new one in and started right up. So i did the same thing when this occured turned the key on and the pump sounded like it was being choked and not how it should and wouldn't prime the whole time and then you try and start it wouldn't work. So i went home and was gonna tow it home came back and turned the key and it worked just fine. I had a quarter of a tank of fuel and its a walbors 255lph pump. Last time i rememeber it messing up i was low on fuel as well. Do you guys think that the pump is getting way to hot and shutting down ??? Should i put half a tank of fuel in and see if it does it as well ? ? Or do you think its pulling to much power through the wiring ? I know nothing about fuel pumps and what is all entitled in making it work. As far as i know its the stock wiring as well. Any help is appraciated thanks. Oh yea motor should have around 500 530 at the crank ish and i'm spraying a 150 ish shot. Walbors say they are good to 775hp at the crank
