On older vehicles this is usually caused by 12v power still getting to the coil even after the key is removed. The coil is the thing that changes 12v to a very high voltage so the spark plugs can work.
I wish I was more familiar with your particular engine but since you already changed the switch (first of my idea too) you may want to see why there is power still on the "run" side of your circuit before you start back up again. The lights staying on is hinting to me that something is still allowing power into that side of the circuit breaker panel even after the key is removed.
The key should have an Accessory position which usually turns on most systems like the radio and even the lights. A Run position which is the position that the key is normally when driving that will keep the accessories on and also give power to the ignition circuit which powers the coil. And a start position that will turn off most accessories while giving most of it's power to the ignition circuit and the starter motor circuit.
These positions have separate areas on the fuse panel and I suspect that somehow 12v is being accidentally back fed into the ignition side of the fuse panel and apparently all the time.
