Those original coils are well known for doing that too......just like your experience in cars. Its a good move anyway to change them.
But both coils giving out at the same time doesn't seem likely. However I don't see the K running too well on just one coil.
Still never really worked out if its fuel supply being disrupted or the ignition side being disrupted. Check when it happens again by opening fuel tank and seeing if the fuel is being pumped back into the tank while you have the starter engaged. No fuel means it's not the coils and you should be looking on ignition control side and fuel supply side. There have been instances of poor connections to the electrical fuel pump plug under the front left of the tank causing this cut out and I have been there with it. The wires can even become detached from the metal pins.
