No pressure in shower

HELP!!

Getting ready to leave on a trip tomorrow morning. Was just doing my usual checkout before trip, and found no hot/cold water pressure in the tub/shower. All other faucets have great water pressure. It worked just fine two weeks ago on our trip.

I don't know how to troubleshoot this. Looks like the water line from the pump and hot water heater vanish somewhere behind the kitchen sink, bathroom sink and toilet.

Any help would be great.

my first search missed some threads. I now found a couple. Let's see if there is already an answe.
