Dishwasher problems help?

My friend has a 3 year old whirlpool dishwasher Model DU1055XTV21 That wont stay running.. tried to run the diagnostics on it and it also just shut off ...do you think it is the board?
Update: Checked all the troubleshooting that is with the dishwasher and there is nothing for this symptom.. starts runs for a few minutes then totally goes off, no lights nothing.. any ideas?
