Did it act like it was out of gas? Shut down, wait 10 minutes then it started back up? If so, may be a vapor lock issue? I experienced this with my Dart. I moved the fuel line 3/8" away from the passenger side header, never happened again.
It was longer then 10 minutes. Fuel line has been that way for many years and never had this problem. Being that it is original tank and lines I ordered a new tank and 3/8 line. Hopefully this will resolve this issue.
