The toilet bowl is filling up very slowly. When I take the back of the toilet off, I see that there is only a little bit of water going into the fill up tube. I then found that if I turn off the water to the toilet and then turn it back on again, the water pressure is perfect and the toilet fills up normally. Do I need to change the water shut-off valve or is it something in the tank that needs to be fixed?

Some fill valves turn the water down if they detect a leak, sounds like yours is malfunctioning, that or scale, rust, gravel sticking in the valve. Some can be cleaned by turning the water off removing the top of the valve and turning the water on just a little. Putting a cup on top of the valve allows a higher water pressure. If the fill doesn't improve a replacement will be needed. Not all fill valves can be cleaned.
