Hey everyone am trying to diagnose some form of electrical problem. I will do my best to describe the situation.

Since I picked the car up it has always taken a few extra cranks to get started however hasn't had any problems starting just takes about 4 cranks to get going. Recently it has stalled on me a few times at various points driving, once while coasting along doing about 30km/hr and a couple times while stopped idling.

After stalling on a few occasions I have tried restarting however just sits cranking over... After a few minutes sitting there it managed to start back up. Twice I have had to jump start however took a few minutes even with this so not sure the jump starting was the aid in this situation or simply the time sitting.

Tested batter (good condition, tested @ 550 CCA) tested alternator (reading of 14V) battery terminals/connections in good condition.

As a note to all this I am running a Vortech supercharger, 11psi with AEM EMS...

Any suggestions / prior issues similar would be helpful in diagnosing the issue

 

Don't think its electrical at this point can't find any form of lose connections or bad grounds... Any ideas on what this could be????
