When the temp is 80 or higher outside, while driving engine dies. While in process of dying if I push the gas too hard it just dies out but if I barely push gas I can make it about 2 minutes before it dies. After about 10 minutes of waiting I can restart it and drive about 30 minutes before it dies again. I replaced the ignition control module and ignition coil but that didn't help...any ideas what is causing this engine or fuel problem? Thanks!

check your fuel pressure when it happens if you can. that particular year had a problem with the harness going to the fuel pump. alot o f the replackement fuel pumps come with a ppieceof harness that is about a foot long that must be replaced along with the fuel pump. it would be a good idea to change the fuel filter as well...if there are no service engine codes it could also be the crank sensor or cam sensor...... they sometimes will not set a code but go bad....
