sounds like you got somethin in your tank or lines. Do you only have one fuel filter? Did you change your air filter by a chance? Start ther then let us know

I had to replace the mass air flow sensor. $ 150. the engine would shut off when driving too.changed fuel filter only worked for a day. The sensor is just after air filter.

Check if any spark or fuel.

Sounds like the fuel pump got air in the system. You may have to bleed out the air. Then it will run. Check the fuel tank for fuel first.

Hello, 9-10 volts is not enough to keep a modern vehicle running. Taking in consideration the age and model of this truck, it could easily be an alternator failure.
I hope this helps.

Possibly faulty ignition module is the problem, stalls when engine is hot when you sit for a while it cools off and runs again until it heats up again, those are usually the symptoms of a bad ignition module and after a while it may give out all together and not run at all, usually if the module is at fault it shuts down the fuel pump so the engine don't load up with fuel, do to when engine continuously cranks over the injectors never stop squirting fuel and flood the engine do to lack of spark which is produced by the module, this could possibly be your problem.

no codes. most direct components changed.
computer. take it out or have the truck towed to the shop/dealer to test the computer.
