Okay so before we start. Car was supercharged at 10000 miles (80,000 miles ago and no issues to date).

Less than a mile from leaving my house three weeks ago the car stalled out while turning at a sharp turn. Would not turn over and had to get jumped.

Two days later car was idling in driveway and stalled out would not turn over until fourth try after that drove fine.

Three days after that had battery tested and it tested okay with a hand scanner. However, had a repeat of the same issue on the first day.

Replaced battery and no further issues

Seven days later I have had a repeat of the first stalling issue however I did not make it a quarter of a mile out of my driveway.

With the car having a custom dunk tune that is locked my Ford dealer cannot log into the car and see dynamics etc. To give me feedback. Can anyone ask any questions of point me in the right direction?


Details to consider:
Car has not driven any different under any circumstances.
No surge in idle.
No knock.
No funny noises.
No check engine light.


Most recent stall this morning was a bit off by comparison.
The car was at 3000 rpm's and I was about to shift into the next gear when I lost all power from the gas pedal (still firm not loose) as the other situations. The rpm's continue dancing to slowly drop to normal idle speed and I turned the car off to turn it back over as usual it would not crank until fourth time.

Try resetting security system. see link then check fuel pressure with a gauge you may have to contact supplier of blower to see If there are any software updates as that may be a problem as well.
