While driving, the traction control light is constantly on and every few minutes, the tach and speedo drop to 0 then goes back up to normal. Once or twice, it seemed like ignition or the injectors cut for less than a second, then cut back on. This started happening yesterday.
An ideas what could be the cause?

 

Sounds like a battery problem. Check your terminals and clean/replace as required. Does the radio cut as well? Any other drop outs?
If the battery doesn't do it, check the electrical connections for snugness.

 

Y, it was a loose positive batt terminal. That should've been the first thing I checked instead of assuming the worst.
Thanks for the help.
