I have 400 psi Enforcer. Today Turned on vac 2 no problem, turned on vac 1 and lost all suction and vacuum sound higher revs.  Turned all off and vac 2 working fine but turn on vac one and suction lost again. Later in day first attempt with vac 2 is no suction but second attempt ok. Lost for an answer and Ashbys closed. Any thoughts?

Have a look at the vac motors sometimes the foam gasket sucks in and then you will lose suction, you need to loosen the motor and reseat the gasket or replace it.
