What might be happening is the voltage is dropping below the minimum that the receiver needs and shuts off. This is known as browning out. What causes this is the BEC voltage in the MFU dropping below that minimum that the receiver needs to run. One way to test this, which is kind of tough in our situation, is using an external power source to power the receiver. To do this you would need to use a y-harness since we use all of our slots in the receiver with the MFU and you'd have to disconnect all the red wires coming from the MFU to go into the receiver.
