Pcm Fuse???

Pcm Fuse???
Fuse 24 In The Power Distibution Box That Controls My Powertrain Control Module Keeps Blowing Out. My Truck's Engine Just Stopped Running The Other Day. I Found The Blown Fuse And Replaced It. It Cranked And I Leet It Sit And Run For About 5 Minutes With Now Problem. Then After I Drove It About 2 Hundred Yards Down The Road It Shut Off Again, Same Fuse Of Course. I Realized I Probably Shouldn't Have Tried Another Fuse But For Humor I Did Anyway. This Time It Didn't Even Crank And It Had Blown Out. Is This The Control Module Or Most Likely Some Freak Wire Shorting Out? Any Help Would Be Appreciated.

I just found the thread where a '99 was having similar problems.
This is a bit different. I did not get the reply until after heading out of town, so I am sans EVTM until THUR.
Take a read through the thread. Fish-on-99 found this to be a problem with teh trans connection.
Don't know if the weather is holding in your location, to take a fishing expidition under the truck for the trans and HO2S circuits.

Exact same fault.
Pay particular attention to the O2 harnesses where they may contact either hot exhaust components, half shafts (if 4X4), and wherever harnesses make a sharp turn around corners.

Good job finding and fixing the fault. Thanks for posting your resolution.
Did you happen to take (or are able to do so) a photo of the fault site? Such a pic can help future owners looking for the same fault.

The picture, even if in the fixed state, with a circle around it, will be very helpful . If you don't have time to edit them, you can drop them to me via an email in my profile, and I can edit them up for you. Resoultions are lacking that much on the more severe items, I am willing to help out if it, if you don't have the time.
