Unhappy Electrical problem

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.


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

Start with new gas or the plugs.

Do the idle learn procedure. Maybe the change in weather is messing with the ECU until it adjusts.
