Premiere Pro Renders Not Playing

[Jericho27606]

So I got Adobe Premiere Pro last week and have been editing a video. It is around 16 minutes long and everything was going great. When I rendered the video it didn't take to long and was fine. But when I open the rendered file that was on my desktop it plays the first 3 or 4 minutes and then automatically skips to the end. Each time I render it more of the video is able to be played back. The problem is on the scrubber at the bottom when watching the finished video it shows the full lenght of the video but can only play back a limited amount of that video. I've tried looking for similar threads and just videos helping with rendering problems in general and can't figure it out.

What render settings are you using? What is the format of the source file(s)?
