Default Car keeps stalling after sitting idle!?

Problem. I'll drive the car for a good while 30 minutes or so. If I let the car idle for more then 10 minutes, it starts stuttering, kinda like there'* not enough fuel. Also if this helps, if I go inside a store after driving it for a little while, it'll have a hard time restarting. Any help would be greatly appreciated.

Hard start hot can be a bad FPR. Pull the rubber hose off the fuel pressure regulator immediately after shutting off engine. Look and smell for gasoline. If you find gasoline, replace the FPR.

Your problem may also be electrical. Carefully check both ends of both battery cables (peel back insulation) for corrosion. ICM, PCM grounds and ground buss should also be checked.

ok bill I will do that. Am i looking for just a slight hint of gas or a strong odor? Because I did this last week, but it wasnt an overwelming smell and I didnt see any gas leaking out. If it helps, I have 3 codes that pulled up. po446 which they told me was an evap solendoid, po106 which is a map or mass air flow sensor, and a p1441 evap system flow non purge condition. I'm sorry if this is all jumbled up but i just wanted to see if any of these codes could be a culprit as well. Thanks

You are looking for a strong smell of gasoline right after the car is shut off. It evaporates quickly.

Check the vacuum lines to the purge canister to see if one is loose, disconnected or rotten. MAF could cause your problem, too. You could try cleaning it carefully and see what happens - iirc, the procedure is in Techinfo.
