My truck has done this 2 times now... all gauges and engine blink off for a second when driving . Then as soon as I see all my gauges swing to zero and feel a hesitate in throttle it comes back to normal. This only lasts for one second. Any ideas?? While driving I turned off key and then back on and it acts the same as when it blinked out.

 

Check the ground connection on the drivers side battery. The ECM or (Engine Control Module) grounds here and the connection could be loose or corroded.

 

Well I took off every connection and cleaned them up with wire wheel on my cordless drill... everything is allright now.

 

Also, how old are your batteries? When they start to go, they cause a lot of problems.

 

That's great, stop further corrosion with battery terminal sealer. Comes in spray will prevent corrosion from forming on terminals.
