Hello,

I have never heard of your vehicle and neither of our two reference guides shows a listing for your vehicle, but I'm pretty sure we can diagnose the problem anyway. This sounds like it could be a problem with your vehicle's Crankshaft Position Sensor (CKP) that is starting to fail. What happens is the CKP on your vehicle has two coils in it and when it starts to heat up they will start to short across against each other. Then when the CKP cools down a little it will work again. I have included some links below for you to go to.

Please go through these informative guides and get back to us with what you find out and how everything turns out.

Thanks
