My car after driving awhile, will start choking and leaves me stranded up to 40m on 1999 Pontiac Grand Am

I have had 2 catalytic converters put on since Jan.'11, alternater, map sensor, 2oxygen sensors, coil pack housing replaced, 2 sets of sparkplugs and the list goes on!!!! Codes are 171, 1171 and 463. I do not know what else to do because I have run out of funds. Today had a fuel pump put on and Sat. a coolant temp. sensor. The temp.needle is reading higher than before but not hot and I was getting only 250 miles to the tank. She is still somewhat sluggish or seems to not have the power when on the interstate..... HELP!!!!

Please, try to find a shop who knows what they are doing. if this was in my State, the shop or shops would be questioned by the consumer protection authorities for doing such a poor, poor job. If you have a code P0171, Then you have a lean running engine. Here is a link to an article I wrote about code P0171, print it out and find a shop who understands what I am talking about, code P0171 is common code, but it takes real inspection, not just guessing with parts to fix it. I feel so sorry for you. here is the article: -> http://repairpal.com/OBD-II-Code-P0171-and-P0174 here are some shops to try: https://repairpal.com/directory?address=23834&car_brand_names=Pontiac

Thank you for responding to my question. I had the fuel pump put on and drove her for about an hour and then parked her for the evening. She was sluggish at times and I worried that she was going to cut off while going down the interstate. I drove to my job the next day and upon leaving she would not turn over and it had to be towed. A new one was purchased from Pep Boys and installed. I'm crossing my fingers that I will not get a repeat. My concern is about code 1171 and 463 that continued to show itself along with 171..... Could it effect any of the work that I already had done or create a new one if it is an issue that has not been corrected? Thank you....Thank you & Thank you
