I have a 91 Chevrolet C15 V6 4.3 2wd TBI 5 speed. After driving for a long time, it just dies. It doesn't cut right out it gradually will just die. I replaced the ignition module and fuel filter. The problem is after a long time it loses fuel to the throttle body. If you wait 5-10 minutes you can start it back up until it dies again. It consistently does this. I am having a new fuel pump put in it but would like to know if anyone else has had this problem.
