Answer-2
They do so because they have been Commanded by Almighty Allah to keep fast during these hours. Muslims having attained the age of 15 years must keep fast provided they are not ill, or insane, or travelling long distances when it is diificult to keep fast. They keep fast from a little before dawn to sunset. They don't eat, drink or touch their spouses that results into sexual urge. They also avoid any unnatural, unethical, immoral activity, though all these activities are forbidden in Islam all the time. However extra care is taken to attain Taqwa and piety during the month of Ramazan. The Shias keep fast 10 minutes earlier and break it ten minutes later than the Sunni Muslims.

Ramadhan
From sunrise to sunset during the month of Ramadan, Muslims do not eat or drink.
Muslims wake up an hour or two before dawn and eat. Then they fast until the sun sets. They then break their fast. Contrary to some beliefs, Muslims do not "pig out" all night, then sleep all day. Muslims rest at night just as usual, and may take a nap or two during the day to keep their strength up.
Muslims fast through the day time period from Dawn (just before start of sunrise) until start of sunset.
The holy month of Islam in which Muslims fast between sunrise and sunset is called Ramadan. The holiday is a time of spiritual purification, which is observed through fasting and prayers.
