Unplug the machine.
Open up the control console.
Check all connections for corrosion (often a dull coating in a pin), poor crimping of wires/connectors, loose pins or if they have backed out of the connector.
Disconnect and reconnect all connections.
You could try getting some electronics contact cleaner and cleaning the connectors and receptacles with a tooth brush. Just be sure all the solvent has evaporated before reconnecting.
Check the circuit board for cold/loose solder joints. Pin holes in the solder, a dull gray color of the solder or by wiggling the component on one side of the board you see it's leg move in the solder.

If all else fails replace the control board but this is a gamble.
It could be the relay contacts that start the motor are going.

It sounds like you have a bad connection in the control console.
These can be a pain to find and often depend more on luck than skill.
