Could be several things, including a bad element or thermostat, but I think you may have a broken dip tube. The dip tube carries the new cold water to the bottom of the tank, if it breaks off the new water enters at the top where the hot water is exiting. It quickly mixes and will lower the temp of exiting water considerably. The dip tube is located inside the cold water inlet of the water heater.

Three hours is the average time to run the hot water per day so if you have a 1500 watt tank you will pay about $13.50 a month <<>> A 1500 watt water tank is not going to heat much water. The average home hot water tank operates with 4500 watt elements in it. To get an accurate price use 4500 watts as a starting point.
About 40-70 psi.
Start with an almost full and fresh water tank. Turn the water heater off and let the water cool. Dilute 1/4 cup of household bleach for each 15 gallons of tank capacity in to a gallon of water. Add the chlorine or water solution to the water tank. (Do not pour straight bleach into the RV fresh water tank. ) Let the chlorinated water run through them for 1 or 2 minutes one faucet at a time. You should be able to smell the chlorine. Make sure you are using the water pump and not an external water supply. Top off the RV fresh water tank and let stand for at least three hours over night is better. Drain the system completely by flushing the faucets for several minutes each. Open the fresh water tank drain valve to speed up emptying the tank. Open the hot water tank drain plug and drain until it is empty. Close all valves and faucets and drain plugs. Fill water tank with fresh water. Flush each faucet for several minutes each repeating until the tank is again empty. (Make sure you are using the water pump and not an external water supply.) Fill the tank again. The water should now be safe to drink but if the chlorine odor is too strong you can repeat the fresh water flush. Your RV fresh water system should now be safe to use.
If you are going from the pet-store's tank to yours you should place the whole bag into your tank for at least 30 minutes then release the fish. If you are going from your tank to another tank you should wait until the tanks are the same temperature then go from one tank to another.
If the hot water tank is off it is possible. It is also possible for the cold water going to the hot water tank to freeze. Insulate all pipes that are exposed - or let them drip (this is more expensive!)
The hot water runs out after 5 minutes because the water heater tank has a limited capacity and can only hold a certain amount of hot water at a time. Once the hot water in the tank is used up, it takes time for the heater to heat up more water, causing a temporary shortage of hot water.

3 minutes without any equipment, 45 minutes with a tank and regulator and indefinitely with a snorkel
To safely introduce daphnia into your fish tank, first acclimate them to the water temperature by floating their container in the tank for about 15-20 minutes. Then, slowly add small amounts of tank water to their container every 5-10 minutes for about an hour. Finally, gently release the daphnia into the tank, making sure not to disturb your fish. Monitor their behavior and remove any uneaten daphnia to maintain water quality.
The time it takes for a hot water tank to heat up can vary depending on the size of the tank and the power of the heating element. On average, it can take anywhere from 30 minutes to 2 hours for a hot water tank to heat up completely.
