I recently purchased a used 2007 GMC Sierra truck. Was working fine until Saturday. I was driving along and the Service Stabilitrak , Service stabilizer light, and reduced engine power reading came across the screen. The check engine light also came on. I was only able to drive at 10-15 mph. After turning the vehicle off for several minutes everything went off and I drove it again. I happened again after going about two miles. I turned the vehicle off again and waited. the same thing happened and I was finally able to make it home. Help!!! Can anyone tell me what might be the problem.

 

Lots of things. Are any codes being set?
