2005 Sorento Cuts Stalls while driving
We are having a terrible time with our Sorento. Quite some time ago it started losing power in passing gear - not cutting out completely but just losing power to pass etc. While replacing battery discovered that after being disconnected and reconnected after some time it worked fine. We were told this resets the computers. Would drive fine like that for quite some time and then occur again. Unplugging the battery for a period of time would fix the problem for a while. Had been running fine though we did have a scare with the lights dimming on a interstate trip a couple months ago. Never happened again so I don't know if this is related.
Anyway, this weekend while driving through mountains car completely stalled after running fine for about 2.5 hours. Quickly resarted, made it to destination parking lot, stalled and then wouldn't resart. Let sit for a while while unhooked from battery and started fine and ran fine for a day. On the drive back home from the mountain on the 3rd day completely stalled while going 65 mph. Dead on the side of the road and won't restart. Towed to repair shop (car has over 100k miles) Told it was fuel injectors. Replaced fuel injectors, and oil change. Want to change battery and we will do on our own since it's still under proration. Drove home all fine. Drove next day, out to lunch, won't start at restaurant. Replace battery even though when tested said it can be recharged - not dead. Car starts up and makes it home fine. Drive to work fine. Drive out on calls running a little hot. Stalls out again in town and won't restart. Repair shop is trying to say battery cables not tightened enough HA. They don't seem to want it back to fix again.
Any help or ideas?????? Just started a new job after 6 months of unemployment and need this fixed!!!! Thanks.
