For your house, a loss at the transformer requires a call to your power utility. Your breaker panel mains would require a pro.
If you suspect one and your house is fairly recent, on a turned off line I'd check for continuity between the neutral and ground at an outlet. That would be the slot that shows zero voltage to ground normally. With everything else on the circuit unplugged, run a space heater and, on an unused outlet but same circuit, check for voltage between neutral and ground. That should still be zero. This checks that specific circuit between that point and the breaker panel mains.

Or get this for <$20.

Also check voltage between the hot and neutral at any outlet. It should reed between 110 and 130 VAC.

When I built my kitchen out I was required to have two 20 amp circuits, one feeding one side of the kitchen and the other the other side. With GFI protection on any outlets within 3 feet of water. A decated 20 amp circuit for the Frig and dishwasher and I believe one for the desposal.
