Hello and welcome to JustAnswer!

It sounds as if the engine is most likely going into limp in. If the engine controller sees an issue that could cause damage or a safety issue it can limit power. There are dozens of possible causes including electronic throttle control issues, a loss of cam or crank signal, an actual or perceived intake restriction or vacuum leak.

The first step in diagnosing the problem will be to use a scan tool or code reader to see what fault codes are setting and then testing can be done from there based on the findings.
