2003 Dakota check engine problem

My son in law has a 2003 dodge Dakota quad cab with a 3.9 v6 and it through an error that says "ASD relay output voltage at PCM" and the motor stalls out and sometime it wont restart for half an hour...Any Ideas...

Trekkerjmm, have you figured anything out yet? The pcm must be shutting down the asd relay and stalling the engine for some reason.
