Power Cuts out while driving

[recklessspyder]

So, I thought i was having speed sensor issue...dash would light up and felt like brakes kicked in. It happened again today to me going only 5mph and the engine actually shut off. Had to restart the car and it was fine. I suspect that the other two times the car started on it's own because it was actually rolling at a higher rate of speed.

My first thought would be something with the ground....or a connection, but I haven't tinkered with the car in quite awhile, especially any ground contacts.

Searching isn't helping too much. Unless this is a quick fix, this might make me get rid of the X immediately, it's unsafe at this point.

Thanks,
Nic

Agree it most likely has to be a connection issue. I would recheck all the major connections (Battery/Alternator/Jump connections).

My last car used to get crud buildup on the terminals of the battery which would get between the clamp and terminal and cause it to lose electrical connection and would just turn on and off on its own accord. If your battery terminals are "clean" and tight it may be somewhere else. There is so much wiring on these beasts though that it may be a case of ruling things out one by one.

Good luck

Checked the Battery and the terminals definitely were not tight (self inflicted by DIY). Hopefully that was the fix. I think I had a 2010 4.8 with the aero kit picked out though.
