My engine seems to start up and then die every time I restart it when the engine is warm. I have no clue what the problem is and I'm not getting any codes. I can here the fuel pump running clearly......WHEN the engine is running.
it could be the pip/stator inside the distributor or the ignition control module both are cheap fixes
I have MSD ignition....what is the pip/stator?
I'm assuming this thing....
Did you pull codes?
After it craps out, does it always restart as long as you goose the throttle?
When you say Ignition module are you talking about the TFI Module that sits on the distributor?
It's not likely to be an ignition issue.
Has the idle screw been touched lately?
How about the IAC?
You might wanna test the ECT calibration.
It's not likely to be the TFI. If it were, his car would not run at all. It simply needs the throttle depressed manually, which is an IAC issue or a sensor that's heatsoaked and reading erroneously.
OP, how do you know the IAC is 'good to go?' Was it tested with a scope? Sometimes cleaning them will finish them off.
With a hot engine (when it won't idle on its own), you can note the coolant temperature and the ECT (engine coolant temperature sensor) reading and post both up. We can see if the ECT is out of calibration (which can screw with fuel trim). It's not likely to be the issue but since it takes 10 seconds to check, it's something I'd do.
How long does it run poorly before it will idle without your assistance?
That's a lie. LoL. TFI are very well know for causing problems like his. Just do a quick google search and see for yourself. By the way, you must not have much experience with diagnostics. Just did a quick google and bam:

I had chosen to be nice and diplomatic since you're new. The lack of mutual respect is disgusting.
FWIW, we don't have cam or crank sensors. I chose not to call you out on this before.
What's the point of that link? The TFI's are heat sensitive but they lead to a no-spark or a high-RPM spark-out. Because he CAN get it to run when it otherwise will not by simply holding down the gas pedal, the TFI is not indicated. And once it did run, the TFI would only get hotter. The car would eventually shut off and never restart.
Failing TFI's reach a thermal limit and shut off. It sounds like he can drive as long as he wants - the trigger point for this issue is his having to restart the car after a short stop.
I could go on but it's not my style. I normally am very tactful when I correct someone, and even more careful when I question something or someone. It's a classy approach that might be worth a shot.
