All fluids are normal, 110,000 mi., serviced regularly, am suspecting the power steering pump/steering rack. Runs great, shifts great, problem lessens after 30-40 minutes of driving but is still not as smooth as normal. Engine sometimes feels as if it wants to die while stopped, although never has, higher rpm seems to eliminate the noticable sensation. Thanks TDM

It is one of 2 things fuel pump or Crank Shaft Position Sensor. Best bet would be the Crank Shaft Sensor, and what that does is tell the computer where the crank is and when to fire the right plug at the right time

it could be an o2 sensor. it could also just need a tune up

need to replace the sensor at base of colum steering wheel sensor

sounds like your fuel pump, normally fuel pumps die gradually not just like that, so best check fule pump fuses first, also i can not remeber if these have a fuel cut off switch, this is normally located arround the fire wall it looks like a red or black rubber button, if you have one you can press that and see if that sorts it, if not then it more than likley is the fuel pump and will possibly need replacing, but check the other things first, better a new fuse than a new pump...hope that helps a bit
