How much fuel have you run in it? Could be father time has got you. And could be air leak some where. The list of could be's is long and hard to do with out more info. First, richen up the HS a little. How old is the glow plug? They do go bad after a while. Why do you think they cost so much? Try this and get back to us soon and let us know.

When does it die? When accelerating, braking, coasting as these can all be caused by different problems.

Been down this road before. If it only starts and runs when it cool thats trouble. Usually the sign of an engine thats soon to be a paperweight.

Could be all sorts of things, included what you said, but without more information any suggestions would just be wild speculation.

less then a gallion on it, brand new plug. going to check the tank later and also probably but new lines. someone also told me to lean it out cuz i have been running it rich, since everyone says its better to run it rich. also this is my first nitro engine so it is probably user error. also i cant really get it to sustain an idle to well.

The problem is, like I said above, it could be all sorts of things and asking here is just going to make the problem worse because anyone has been given such little information they're just guessing as to the answer because you really haven't given enough information to diagnose the problem.
Then when you start two entirely different threads relative to the same issue but stating different reasons, it further clouds the issue.
I understand you're a rookie, but all you're going to do is just chase your tail with anything you get here.
You really need to take it to someone experienced so they can put their hands on it.
