I put Texas speed and performance long tube headers on my car and got it tuned I did not changed my o2 sensors and now now my engine light came on. I had a diagnosis ran and it said the fuel pump was bad but my car isn't losing any power at all it just every time I stop the car be acting like it want to cut off and sometime it will cut off but crank right back up so do I need to change my o2 sensors and get my car re-tuned?

I would consult with my tuner first.

You do not say if your running a " canned tune" out of a handheld tuner or you got tuned via dyno. The headers have to have for their install usually extensions for the rear o2s and then their deletion in the tune, along with the fronts having code deleted for delayed response due to the length of the headers moving the o2 in relation to their readings.
A good tune even canned should adjust the AFR to improve for the increased flow, many times amateurs have also burn the wiring harness from the rears not routing it safely away from the headers also... What ever "tune" you have must obviously be off, and unless your running the tank dry uncovering the fuel pump and frying it with heat in the tank most likely your pump is OK..... Good luck

Whats the specific failure code?
Did you clear it to see if its a hard fail?
I wouldn't think an O2 sensor would trip a code for fuel pump.

If the code read fuel pump and not O2 code, I would definitely start by checking your fuel pump but it wouldn't be a bad idea to check with your tuner first.
