I put this vehicle in the shop 3 different places. We replaced fuel injectors and cleaned them. The vehicle starts and runs fine. After driving to town (10 miles) and going to the grocery store (30 mins) it will not start. If you drive into the city (1 hour) it may completely shut down on the freeway. I will have to pull over and it will not start. You can go back to the vehicle 1-2 hours later and it will start and run. So, when you take it to the shop, it runs fine and they can't find anything wrong with it. They suggest fuel system problems. I feel like something is overheating, possibly electrical. I would appreciate any help.
