Although the problem would seem temperature related my first guess would be the Lambda system cutting out on you. The next time you have a loss of power make sure the frequency valve is still buzzing. If that doesn't help then you have to test each temperature sensitive device and the wiring or vacuum hose routing to it. Pay particular attention to the vacuum advance circuit.
