Workhorse problems
While driving on the highway yesterday and hitting bumps in the road my instruments, tachometer, speed odometer, fuel gauge would go off and then all come back on a few seconds except for the fuel gauge. It would take several seconds after that for the fuel gauge to return to its original position and a warning buzzer would sounded while needle was on empty. The seat belt light would stay illiuminated the hole time. This happened for the next 8 hours of driving.
Then after hitting a large bump in the road this happened again but this time a warning came up saying powering down. So I pulled off the highway and turned off the ignition. after sitting there for several minutes I restarted it and it ran fine until the next bump in the road. This time the powering down and code J1850 came on along with the check engine light.
It never seemed to loose power except for the powering down warning. It is a 2008 workhorse with the 8.1 and Allison transmission with 16000 miles on it. We just purchased it last month and this was our first trip. Any help would be appreciated.
