Hi Customer (name blocked for privacy). Thank you for asking your question on Just Answer.
Have you had the charging system inspected? Sounds like the truck is running off the batteries.When the vehicle is running at the time of the problem measure battery voltage. If it is the same as battery voltage with the engine off then you have an alternator or wiring problem.
Thank you again for trusting us with your problem.
