Thank you for writing in. There are several issues that can cause an engine to bog down and have performance issues. The vehicle will need to be tested when the issues are occurring to definitively tell what is wrong. Common complaints for the vehicle that have similar symptoms are a faulty PVC valve and a bad throttle body assembly. If any warning or check engine lights come on when the vehicle starts to lack power, you will want to start by getting your vehicle scanned for diagnostic codes. This can be done at most automotive part stores for free. Only further testing will tell. Good luck!
