Some additional info would really be helpful for people to try to understand your issue. More detail is better.
 
Being new here, you should understand, there is lot of good advice here, and there is a ton of speculation, but none of it matters (and you should disregard it), if you don’t give any details. Eliciting advice based on nothing more than “need help with possible reason for my engine out” doesn’t tell anyone anything about what we can help you with. There can be countless reasons for your engine to quit (out). Please give us some details. Many folks here would like to help.
