I heard a squealing noise earlier in the morning and checked the belt which seemed fine (figured it was just moisture as it had rained and was really foggy). Then about 6 hours later I was driving it (going about 50 mph) and it just shut off. I just did make off the road. It would start back up and then shut off again after less than a minute. I had it towed home the next morning after I got off work. When I got there w/the tow truck driver it would not start at all, wasn't even trying to turn over. Now it sounds like it is trying but will not catch. My boyfriend thought it was the crankshaft pulley after looking online so we ordered the part. My dad is looking at it and wondering if it is the remote starter. A few months ago the car would only start using the remote starter button. It happened 3-4 times one day while running errands and has never happened again. Anyone have any idea what it could be? Thank you!
