This unit will run for about 1 minute normally and then the blower will cut out. The contactor for the blower motor has 27 volts at the coil until it cuts out. Then it shows no low voltage. The compressors and condenser fan motors will continue to run until the unit cuts out on low pressure. The blower will not come back on until you cut power to it from the disconnect and then reestablish power. It looks like to me, the only thing that could cause this condition is a bad board. I haven't seen this before and was hoping that one of you have. If you need all of the gauge readings and etc, I have them but I didn't post them since I don't think they are relevant to the problem. Thanks in advance!
