When I turn on the water, it quickly loses nearly all pressure thru-out the entire house. I have a sprinkler system; turned off valve to it and the pressure is still low in the house. I live in a master planned community, and I think there's a water regulator on my meter. At least I think so because there's box with a wire running to something in my meter box. The water is just above a trickle and we can't run the showers, washer, dishwasher all at the same time because it will not supply any water at all. This starting occurring about 3-4 months ago and has progressively gotten worse.

Does anyone know what to suggest?

Pressure regulating valves can and do fail, so ascertaining whether you do in fact have one is very important.

As for the wire, this may in fact be for a remote meter reading device.
