What could it be? Could it be the air intake valve? Please HELP!

Almost every single time I try to stop the car shuts off, it all started a little while back and I can't quite figure out what may be this issue. Also when it rains I end up having problems with my stereo. The sound will not come out every speaker.

Scan for codes and check fuel pressure with a gauge first. Have radio guy check for water intrusion clean throttle plate with choke cleaner on both sides.
