Electrical limp mode?

Hey guys,
This morning on my way to work all of my gauges dropped out and the truck went into a limp mode. Shifts hard, no power, won't really let me accelerate at all and it sounds much different. Any ideas??
Thanks,
Rocky

Sounds as though it could be a failing/failed alternator to me.

Tow/haul and check engine flash intermittently on occasion. The gauges go out and the truck shuts off. Start it back up and the gauges are all down and it's in a "limp" mode. No acceleration or gear change and shuts of again. I have no clue what's goin on 3rd time it's happened in a month now..... Any help would be greatly appreciated guys.

here's a guide to reading voltage.. its real easy

http://swampsdiesel.com/site/how_to_...latageTest.pdf

mine was fine key on, and turning, but once idling it dipped into the 30's.. thats where i'd start. i had a bad alternator that was putting out like 11 volts and it caused a chain reaction through my truck.. dealing with injectors now.. but thats a different story
