I came across this as well:

Hard start; Stalling; Irractic idle and/or loss of power; DTC P1298 all models--95-96 Econoline in wet weather:
Injector Driver Module (IDM).
The IDM converts 12 volt battery power into 110 volts and activates the injectors as directed by the PCM. On some Econolines water may enter the IDM causing the above symptoms. To diagnose, remove the LH battery and the coolant overflow bottle and access the IDM which is mounted behind the coolant bottle. Remove the IDM(both ground strap bolts need to be removed) and shake it, listening for a sloshing sound. Water running off the roof and cowl areas can enter the IDM; there is a service replacement IDM--F6TZ-12B599-AA--that has improved sealing. Also install foam seals (1)F6UZ-13C795-AA and (2)-BA on the back of the IDM.
If the DTC P1298 is alone when performing code retrieval, replace the IDM; if other codes are present, diagnose them first.
A faulty IDM can cause driveablity concerns similar to a malfunctioning ignition module in a gas-powered vehicle. Under load it will seem as if the engine is starving for fuel. If you verify good fuel and oil delivery and pressure to the heads, and the Mass Fuel Desired, ICP, IPR and Fuel PW readings climb while the RPM's drop, suspect the IDM.

Its behind the inner fender cover. You have to take the plastic inner fender out the look toward the door and youll see it.

IDM for Ford 7.3

Auto Computer Exchange - Auto Computer Superstore - Cheaper than dealers and mechanics.

The price has gone up to $250.00. Mine has been installed since June. It works fine and they are good to deal with.

It is located in the fender behind the F350 emblem. You have to remove the fender liner to get to it.
