Don't want to jump to conclusions, but...

While driving in traffic this afternoon in 2nd gear about 2.5-3.5k rpm the car in from of me changed lanes so as usual I give it some throttle and the car completely bogs. That's weird, I think to myself and I give it gas again and it does the same thing. Then I hit it again and it seems to be fine.
Also, before last week the car on the highway would average 30 plus mpg now I can't get it to average more than 28-29 mpg. I thought that was a bad tank of gas but have had 2 fill ups since then at different stations.
Could this be the begining of a common 335 problem. (I'm not gonna say those 2 words yet.)

My car was built in 09/06 and now has 7000 miles on it and has always started within a second.

Get to your dealer and order that fuel pump now.

My car especially does this at times whenever I have the AC on. I don't notice it as much with AC off but still happens. I wonder if loading V1.45LBT will solve this problem. Been having it for 2-3 months now and fuel pump hasn't failed completely yet...

The AC was on at the time, but it happened the instant the gas was touched and did not throw a CEL. If it happens again, I'll switch to 1.45lbt.
