About a month ago, the dishwasher started stopping mid-cycle every third time we ran the machine. The start/resume key would be blinking (not rapidly but just a continuous blink). I thought someone kept opening door by mistake. I would just hit resume and it would start over and usually finish the whole cycle. This past week it just went dead - no lights could be illuminated when touching the keypad. I flipped off the circuit breaker for 5 minutes and the machine came back to life. I could illuminate any button when touching the keypad. I tried to run another load but again it went dead mid-cycle. I reset the machine and ran system diagnostics on it by selecting normal and heated dry a couple of times. The test ran for about 20 minutes and again the machine went dead. I can always reset it by turning power off and can always get machine to start a cycle again. I also just ran the keypad check by opening the panel and unplugging the ribbon. The drain motor started up for 2 minutes after I restored power and closed the door. I am wondering if this is a control panel or control board issue? I wish it was just a thermal fuse issue but I don't think I could get the power back on to the unit if it was a blown fuse - could I? Any thoughts to what my issue is?

I replaced board, but same problem returns where it stops midcycle with no blinking lights. The only way to get it to work again is by turning off the power to unit for atleast 5 minutes. Could it be the control panel or something else?
