Half way throu my dishwashers

this happens due to the high electric current requirement of the dishwasher and it is not receiving that required current so it try to start but due to lack of required power it shuts off the current in whole house.
get the electric curren line checked out in your house.

and to check the current in your dishwasher check out this instructions
You will most commonly measure two electrical parameters when you're troubleshooting your appliance: resistance (measured on units called "ohms") and voltage. Typically, both of these measurements are made on a single meter called a multi-meter, which you can set to measure either ohms or voltage.
This shows how to measure resistance. Resistance ( or continuity ) is measured in units called "ohms." You'll commonly want to know the resistance of things like bake elements and solenoid coils. For example, a good bake element typically has a resistance of about 30 ohms. If your oven's not baking and you measure the resistance of the bake element and the meter doesn't move, then you know you have a bad element. A simple ohm measurement can save a lot of money and a possible headache :)

Amp meter: Here's a clamp-on amp meter (or amp meter) being used to measure current flow through a wire. This is a common test for determining whether or not a gas oven igniter is good or bad--only way to really know is by measuring its current draw and comparing to rated draw. You'll also want to measure current/amp draw in cases where you have an electric motor that runs for a few minutes then shuts off on it's built in safety to see if the problem is with the motor drawing excessive current.
Volt meter: This picture shows how to measure voltage. A voltage measurement at the outlet should the first thing you do whenever you have an appliance that is completely inoperative...a simple power test is required if your electric dryer is running with no heat to make sure you have both powers at the dryer

thanks.
