    Agreed. While your manometer is hooked up to the inlet, turn on other gas appliances and see if it maintains pressure. Who knows maybe they did a bad load calc on their gas line?

    It's odd that it's only happening at night, especially " (5 times a week)".

    How is this unit Vented? From what you've supplied, I'm assuming that this is a"Standing Pilot", & not Spark, or HSI.

    Have you checked the thermocouple, as far as position, being burnt, properly mounted to the Gas Valve etc.?

    How is the Flue Terminated? What about the Flue Pipe, ... any Birds nests, or Illegal Immigrants hiding out in it?

You may have just enough pressure to run one unit at night or maybe that unit is getting moisture in it at night and freezing, snuffing the pilot. Could be a bunch of things but I like Hvac Marcs idea best. Eliminates all the problems that go with pilot lights( including possibly your issues) and at whatever your customer pays for propane will pay for itself decently quickly. Payback is even quicker if its a business(florist?) and you count lost product, which I would. If nothing else you may have to show up and test the system when its in the 20s and see whats diifrent at that temp

    I was going to say "Second Stage Regulator", but Makeitcold, kinda beat me to it.

    I've seen Second Stage Regulators Lock Up, &/or run out of wack, due to moisture that became lodged in them. I've also seen Second Stage Regulators Fail, because they were Old, & just didn't want to work very well when it got below freezing.

    We have had similar problems like this for the last couple of years with Rego brand second stage regs. With no load, they creep up to 20 and higher, then when the equipment fires, they drop down below 5, and the equipment locks out. Im not saying this is what is going on here, but just putting it out there. We have changed many Rego regs over the last 18 months.

    They will soon forget how long it takes, but they will always remember the quality.
