Fortunately when the Crankshaft Position Sensor acts up, it just causes a problem starting.... I had that happen last year at the track when I was in line and went to re-start the car... started and ran real rough so I turned it off and re-started.... it did the same thing and I gave it some gas and it cleared up... I didnt see the CEL and made TWO runs after that with no issues before I saw the CEL and quit...the CEL cleared when I started it up to go home, but I let anyway.... the OBDII showed a P0335 when I got home....

Did you get a CEL and what code if so? I think your on the right track with the Camshaft Position Sensor...
