could it be electrical? my dad and i took it out to test drive it and we couldnt have been going faster than 20 when every light on my dashboard lit up for maybe a second. it did that a couple times then stalled a little after that. when we were on the way back home we noticed it stalled everytime i turned on the blinker. Is there something i can do at home or does it need to go to a repair shop for a diagnostic?
