    I have pretty much the same problem.

    I could be driving stop the truck and then when I get back in to start it up (after 2 mins) it wont start, it is as if the engine immobizer is restricting the the engine from firing up. Also some times at traffic lights that are on slight inclines the vehicle computer system suddenly says Traction Activation and accerates very slowly (no matter how far you push the accelerator.

Could be the fan switch, the resistor, or the blower motor. A mechanic would check for voltage at each point and also the ground connection for the motor.

Well, if you jumped the battery and it started, maybe you need a new battery. Get that checked out first. Also, when was the air filter replaced?
