Driving down the highway going about 80-85 mph and the engine just shuts offs. Get dash message to pull over engine has lost power. RPM gauge is at Zero (0). I eventually am able to pull over to the shoulder in which I shut the engine off. Tried to restart and engine wouldn’t restart. After 5 min pass, I am able to start the truck back up and drive off. But now the confidence that my truck is safe to drive on the highway has been shot and I worry if I should even take it on the highway again. Took into local Toyota dealer to have it looked at and of course, service technician does not get any computer codes saying what happened. They could not duplicate the event, so they are putting me back in the truck with no explanation as to why it happened and if it will ever happen again. There was no true fix for this issue, just to bring it back it it happens again. The chances that if and when it does happen, there probably won’t be a computer code again.
