my 8 keeps stalling

For about a month out the blue my 8 would hesitate badly until the temp hand was registering normal. On friday morning after driving about 10 mins it seemed to loose pressure, the cel flashed and begun to rough idle I got to the light and it stalled. I pushed it to the side and after about 30mins it reluctantly started I had to keep accelerating in order for it to make it about a mile to a friends shop. The code read P0302 I changed plugs and coils it runs smoothly for about 10 to 15 mins and still does the same thing. Btw while rolling I can pop the clutch and it will restart and keep going. Anyone having similar experiences and what did you do to resolve the issue?

bad cat. run it hard again, after 15 minutes look under the car and see if its glowing. sounds like your catalytic converter is going out. either have it replaced, or swap it out with a straight pipe

I don't have a flashing CEL like the op does. Mine used to stall when the temperature gets over 100 degrees and my a/c is on. Now, even though the temperature is still hot, i don't turn on the a/c anymore and my car does not stall anymore. I don't know if i have a bad cat or not...i may have to have that checked.

Possible, flashing CEL means misfires, misfires kill cats, rather quickly in some cases.
I would check the cat first.
You could get the pump checked, I'm not sure if that can cause misfires, I don't think so.
It's a good idea to change wires with plugs & coils as a group every 30k miles.
Good luck.

There was one day my car would do that, rough idle (well this happened a few times) after a few hours of driving / the car was on for a while. Ultimately ended up being the engine lost compression = new engine.

EDIT: It would stall / die randomly at lights when I was giving it no gas. Then it would not crank until it cooled down.
