I have had the same problem on two ocassions. Your compressor is going bad. After having the compressor replaced (twice), everything was fine. Once it finally levels, turn the suspension off using the switch in the left side of the trunk. Wait awhile. If it drops again, the front bag(s) are leaking. Else the compressor is too worn out to lift properly within the 90 second time limit and the computer is cutting out to "protect" it; will need replacement as is not user serviceable. They go for around $160-$180 (4/2007). Suspect your bags as well, cause if they're leaking, that will cause the new compressor to overwork and fail again.
Your front air suspension bag has a leak in it.
Your air suspension bag has a leak.
The compressor is located on the front passenger side of the engine compartment just in front of the battery. (man, have we had problems with the whole suspension system!)

It is in the right front corner of the engine compartment (passenger side)
how do you no when you front air suspension go
The front suspension is steerable.
All but the springs. The springs match the weight of the engine and accessories.
To the best of my knowledge this truck uses the front suspension called "Ford twin I-beam front suspension."
On a 1997 Ford Expedition : ( NO ) not on the front suspension It could have the REAR load levelling air suspension
