Help.. I have a 2007 Silverado. When I'm driving it feels like it looses power and sometimes just shuts off. Other day it just shut off while driving on the freeway. What could it be??

Your oil gauge will not show pressure when the engine is not running or you are cranking it. (It will rise as you crank but not normal operating range.) If you have fuel flow to your injectors, you could eliminate that, but it needs to be checked when the vehicle will not start to eliminate a blocked filter or junk in the pick-up line in the tank. When the truck will not run or start, do you have spark at the plugs? Intermittent problems are the hardest to diagnose. If you want your truck to run right, drive it into a garage to show them the problem. If I was working on it, I'd first make sure you have spark to the plugs, have unrestricted fuel flow, check the computer error signals to see what it would tell me, then if all are working, start with the electronics. Make sure all the connections are secure, clean and sound. The computer boards then need to be checked. If and when they get hot, they expand and a small crack may disconnect a vital function on the boards. Start with the basic stuff, then work into the expensive parts, which is almost always where the issues are.
