I don't know the correct answer but have you tried restarting the device? Sometimes issues like this can be resolved by restart. Also checking that you are up to date on software.

Just do a basic maintenance every now and again. I like to delete cookies at least every 2-3 weeks, do a full run down of battery and full charge, and a clear out of unused items. Wether it helps with little blips I don't know but its just like a PC, you need to clear out to keep it working at full potential.
Glad it's all working again.

You go to Settings>Safari and tap the Clear Cookies and Data button, then tap the Clear button in the pop up window.
