Recently purchased a 95 Z-28 with a new Gm crate motor and less then 1500 miles on it. Beautiful convertible and love the car, however I drove it home which was over 400 miles one way and it ran great and no issues. However in the last cpl of days I have driven it and it has been running great until I get to a stop light and it will die. It will not start again until after sitting for like 5 mins and then starts right up. Today it did this to me at a stoplight and I waited in the lane with flashers on and it started only to get me to the next stoplight and did it again. Was able to coast into a parking lot and sat and waited and it started right up and I drove it for about 30 mins with no more issues. This car has a new fuel pump and fuel line on it and at times I smell raw gas but unable to find a leak anywhere and may not even have anything to do with this problem. Any one have any ideas on where to start or what this might be? I will note that when driving home it was night and cool out and the times this has happened it has been during the day and temps are warmer. Today it is 80 when this happend! So again not sure even if that has anything to do with it. Thanks!
