Everything works good except the fact that it turns off after 2 hours of non stop driving

When it dies, check for spark and fuel pressure, do you have any codes?

Sorry for replying so late. By spark you mean spark plugs. I have no idea what you mean by codes and the fuel pressure is good

The spark plugs have a good spark when cranking, and codes refer to getting a diagnostic scan many faults will leave a code that can be retrieved and this will help with finding the problem.

Oh ok well the sparks are good, but hold up where is the fuel pressure meter located or is that the litte gas thing that says how much you have? And about the codes: How do I do it? And are you referring to the "Computer" under the passenger seat
