Answer
Hello Billy,
This can be due to so many possibilities. First check that the battery cables are securely connected . Clean them if you can but do not disconnect them since you would then need to input the radio code. If they are OK, monitor the fuel pressure for your fuel pump or pressure regulator may be going bad. If OK
too, chances are that one of the cam sensors is bad.
Of course there are still other possibilities, but these would be the most frequent ones. A scanner will be a great help in this scenario. If you can have it scanned for free in autozone
tell me what codes you get(after the battery cable check, this has to be the next step).
Update me of your progress or lack of if you can. Regards,
Tino
