Ok starts and idle fine then after 15 min of running when i come to a stopping or red light and it idle down it dies. I can crank it right back up and be fine till i get to next stop what the hell can it be could it be i just need to get it tuned. Or could it be something to do with lack of vacuum or what breaks seem to work fine until engine dies

mine did that a while back.only when i came up to a stop.
it would idle down and then die.
i ended up doing a base idle reset and it was good to go.
a easy way to check is start the car and then unplug the iac.if it dies right away its idled down to low and needs to be reset.
have u ever messed with the idle stop screw? hope this helps!

Also you my check ignition module mounter on the left fender under the hood. My 89 did the same thing and it turned out to be the module. When it gets hot it began to idle bad and die. Replaced it and it was great.
