Answer
Hi, Corey.  We should be able to move down the path to sorting this out.

When you say you lose power temporarily, do you mean the engine doesn't accelerate properly or that there is an electrical issue?  Do your best to describe exactly what is occurring.

With a voltmeter, check the voltage at the battery terminals with the key off and again with the engine running.  What is this voltage?
