Rough idle, rev drops till shut down, wont fire up- HELP PLEASE!

last night been driving during pretty heavy rain.
at some point the motor (03') start feeling rough, wasnt stable in idle, slow response to gas pedal till mo responds at all, revs dropped till engine chocked and shut down.

at first I was able to fire it again, later it just couldn't fire up (have starter but wont fire up).

OBD scanner brought up code P0638.

would appreciate your assistance.

many thanks!!!
