Here's my problem. I had a problem a while back where my car just started stubling and then die while driving down the road. I would turn the key to restart and off I went. It done this several times for about 10 miles. I finaly pulled over. Shut the car off and restarted it ran fine for 5 months.

Now I just put a supercharger on and now the surging problem is back. THe car will surge only after a quick tap on the gas and stumble until I let off the gas and then die. Just turn the key and running fine again and this keeps happening with every tap on the gas. If the car is in park nothing, revs fine and never a stumble. If I take it easy car also runs fine. If I keep it floored runs great until I let off gas.
I don't think it's the supercharger due to this all seams like my problem I had a while back.
