It’s concerning to hear about your truck’s power loss after long drives.
This could be due to a variety of reasons such as fuel system issues, problems with the transmission, or even an overheating engine. It’s great that you’ve been vigilant about regular maintenance, but I would recommend having a professional diagnosis done to identify the root cause accurately.
While it could be a result of long-distance driving, it’s best not to dismiss any significant changes in your vehicle’s performance.
Don’t worry, many of these potential issues are solvable with proper attention and care.
