I’d be leaning towards the fuel pump. Sometimes when they heat up after running for a bit they wont pump if you shut the car off then go to restart, till it cools. I seen that before on an Olds. It will crap out entirely soon enough. @ KnnNike, some things just Do Not show up on computer if they fail, like the fuel pump for example, or ignition module may not, etc. I had a CPS go bad on my Pontiac Bonny & never threw a code. Just something to keep in mind.
