It sometimes goes cold when having a shower
Are the pressure ballance taps? If the shower is on and someone flushes the toilet the water will get hot in the shower,if they are not pressure ballance taps,or if they are the cartridge needs to be replaced in the tap.

The issue you have is known as water hammer per se. It is the result of water logged air chambers in instances such as yours. The easiest solution is to turn off the water supply to the house and drain the entire system from the lowest point available such as a hose bibb/water spigot. Turn off your electric water heater if applicable as lack of water will burn out the elements. Once this is done turn the water supply back on to the house and bleed the excess air out of each appliance by turning it on and running both hot and cold water until air dissipates. Another cause may be an inadequately secured plumbing system behind the shower itself. The piping should be secured to some cross member to prevent movement caused by water pressure. A special device is made in extreme circumstances and larger systems called a water hammer arrester which does the same job as an air chamber but uses different principles to accomplish the task. I hope this is of assistance to you and thanks for using Fix Ya. If I can be of further assistance please let me know.

shut off the water from the main pipe.
use a allen screw driver take the handle off the shower control.
pull of the wall cover.
pull out the pin that stablized the cartridge in the control body. (remember how it is, before you take it out. or take a digital pic of it). pull out the cartridge. and bring it to any home center or plumbing store.
install in reverse.

SOURCE: Shower goes hot and cold
If you are having trouble only at the one fixture (shower), and no where else, the problem is most likely in the shower valve...which either needs new cartridges, or a complete replacement.
hope this helps

This sounds like the elements or you just may need to turn the heat up. If it under two years old call the manu on the warranty. They make a good product so they should help you. I would check the heat setting first, though I doubt it is going to be the prob.

does this happen with any other fixture in your house that almost sounds like an element in a hot water heater.
or remove handle and look for an adjustment dial to temper water and adjust it
