Stalling Issue Need Help
97 328i manual. Car runs fine for a while then dies and wont start again. So About a week ago I was driving on the hwy, and my car started to sputter like it had no power. So I pushed my foot down on the gas and it went back to normal. Then after I got off the hwy sitting at a light it sputtered and died. So I turned the kit and it started right back up. Then the next day driving to a friends house same thing, on the hwy starts sputtering I give it gas and it gets better then dies before I can get off. (lucky for my my uncle drives a tow truck). Wont start for the rest of the night. Next day Im in the garage and I try it to see what happens and it starts and runs fine. So not wanting to push my luck I decided to let it run for a while and see what it does. So it runs for about 15 - 20 min then dies and wont start. I cant seem to figure out what is causing this, just looking for any suggestions. I can hear the fuel pump turn on when I turn the key. I got a P1423 code which I had before because of my secondary air pump. If anybody on here knows what this could be any advice or help for info would be great.
