Any time you have have a power wire next to your frame put some rubber hosing (or cut up an innertube) around it. The wire is bound to wiggle (due to driving or flex) and the casing will eventually wear through.

Its worth it to check it out pressure should be in mid 50s. The other common problems for loss of power and sputtering are bad MAF sensors and clogged cats. Do you have any trouble codes on the computer?

to add, if you keep driving on a bad MAF sensor, the cat may end up getting ruined because of said sensor.

check your 02 sensors, they get gummed up when your engine runs too rich.
