When I drive my car in the summer for a while (hour or so), park the car, then restart it in about 30 minutes or so, the engine turns but the car stalls. If I restart it with a little more gas and rev it a bit, it starts but kinda the hard way. The car runs fine after that.

Every once in a while, if I warm start it with the throttle half way, it kinda starts with a "loud noise". I wanna say that the noise might be a slight backfire. Any suggestions?

My money is on a dying fuel pump. When it is hot, it is failing. My 986S track car did the same thing. If I let it cool - sometimes that was a couple of hours - it would start. When hot, I had to pump the pedal, and then it sputtered, coughed and backfired. It would run at idle no problem, but when it demanded more pressure, no go. Longer I let it go, the worse it got. It is an easy DIY-er BTW.

Have you looked at where the filter sits? It is behind 2 huge cooling pipes running along the length of the car!

Not on MY02 and newer Carrera. There is one filter inside the tank on MY02 and newer that never needs changed unless there is some sort of contamination of the fuel tank.
