Maytag Dishwasher Fills, runs 4 sec then stops

My Maytag MDB7601AWW (2007)Dishwasher will fill, then run for 4 seconds, then stop and the display light goes from the 2 hr timer to black. There are no error codes. It will try again on it’s own to run a few more times, each time shutting off after 4 seconds. I have opened the door during these 4 seconds and verified that water is pumping through the spray arms. If I reset the touch pad control panel (which is fairly new), the dishwasher will drain. Any ideas?
