Hi, this is our first trip out this year. When we go to use the hot water, when we turn the faucet on, the water starts real hot, and within a few seconds, it becomes cooler, and the cold water is mix...

Double-check the winterizing valves for the water heater.
Some bypass valve setups rely on one-way valves, which may be built into the water heater connections, and sometimes these one-way valves get stuck or have some debris lodged in them. Typically the one-way valve would be at the hot water output, and even if it were stuck I don't think you'd get unwanted hot and cold mixing if the other valves were set properly, but there may be some other arrangement I'm not aware of or thinking of at the moment.
Is the water heater a "10 gallon" model that actually has a six gallon tank that is heated extra hot and mixes the water at the output to get a reasonable hot water temperature? If so, that mixing valve could be acting up for whatever reason.
