What was the code the scanner retrieved? There are several that relate to the IDM, and don't necessarily mean the IDM is the cause of the problem. When the truck died, did it sputter out, or was it like the key had been shut off?
The PCM needs to see 500 psi ICP, 100 RPMs and no less than 7.5 volts to send a fuel delivery command signal to the IDM. The IDM may need a higher voltage to operate.
A problem with the HPO system, such as bad ICP sensor or stuck IPR can prevent the PCM from seeing 500 psi of ICP. A bad cam position sensor will prevent the PCM from seeing RPM. Obviously, dead batteries will cause a low voltage reading.

Without the error code it's a guessing game though.
