Someone will need to figure out if you are loosing spark to the plugs or fuel to the injectors when it dies. You should be able to run it in drive at home and watch the RPM gauge drop when it dies. As it drops try one foot on the gas and one on the brake to keep it running. If it slowly dies you have a fuel problem, if it cuts off like you turned the key you have an ignition problem. Often times a stalling problem is a dirty throttle body or a sticking idle air control valve which may not show up on a code test.
2000 chevy venture run good but my lights flickers and have to jump. After I jump the van and put my meeter on the battery its reading 14.volts at idle. I can drive around to store cut the van off come out it starts fine leave it overnite and it don't started.
