loss of power when accelerating

No fuel filter on the stock car. Drive the fuel out and fill up with fresh fuel. See what happens. How old are your tires, if you had traction control on it may have cut the throttle due to traction issues. They may have been what you felt.

Ah didn't realize there was no fuel filter. My tires are about a year old. Traction control was on, but most of the time I was barely pressing the throttle when it happened (normal driving). In any case I'll try turning it off and see if there's any difference.

Another note I forgot to mention, about a month ago I drove it on the highway for about 20 miles and I went from 1/4 tank to 1/2 tank. Really strange. I had the fuel sending unit replaced under warranty about 8 years ago, wonder if it has gone bad again.. or could bad fuel cause it to flake out as well? It seems to like to stay at half tank right now even though I drove it maybe another 20 miles since, miles left in tank fluctuates from 149-153 miles.

I wonder if the top hat has broken on your fuel pump

That is what it sounds like. The top hat broke off the fuel pump assembly.

Thanks guys, after reading some it does seem like this could be the cause.

Nissan considers the pickup sock on the bottom of the pump the fuel filter. I've yet to see a auxiliary fuel filter (mod) added to the OE system.
