Do you think it might be the crank shaft ? Cause it's so old that it is running good and then it missis a beat ?

Already did that it goes for 30 to 40 psi never drops from lower then that do u think the crank shaft sensor would make it do that and it never throws a code when it happens

did you change crank sensor? your symptoms do point to that possibility. although the relay clicking may indicate bad ground connection somewhere.
