Spark/oil pressure problem???

I have a Chinese GY6 150cc (actually I have two), after about 2400 miles one of them started to kill at random times. I have replaced all hoses/filters and checked all electrical connections.

I then swapped the fuel pump, carburetor, CDI module, Coil, and voltage regulator with my other scooter. It still dies. It is more predictable now, basically I can start it, let it run for about 5 minutes (idle or driving down the road), then it dies. If I remove the spark plug immediately and hit the starter, I have found that I have no spark when this happens. If I wait about 5-10 minutes, it restarts no problem. Someone at the factory tells me this might be oil pressure related? Any thoughts?

This problem is probably caused by the flywheel shorting out two wires
that come from the magneto. You should check this out to be sure tho..

aparently it sounds like thats the problem...
the stator and magneto...
because if its not the cdi or the coil
usually its the stator and magneto...
mount a new one and it should help your problem...
i recommend you to mount an 11 tip stator
since you have regulator...or if you want
you can use the little one from NCY that has 4 tips
it puts double the electricity in your scooter and its regulator compatible
and improves the scooter's run...
