Test the CRANK sensor with a scope, this can be tough, but it can be done by watching the signal while driving the car when this happens. Then take a snap shot of the waveform. It's not hard to do either. Here's a pic of how it should look if it's good.
Thanks for your question,
Crank shaft position signal for #1 cylinder to the computer. When the sensor wears out, it can no longer withstand the heat that it's subjected to and does exactly what your symptom is.
Under $100.00 should do it for part and labor
Thanks again for your SUPPORT,
