Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
The solution that you should try first, is that the belt might need readjusting and lubrication (with the special, non-grease, lubricant these treadmill belts generally require.)
The belt should be adjusted, generally speaking, so that it is loose enough that it does not quite slip, but nearly that loose.
If the belt is adjusted (or, has shrunk up with age, and lack of lubricant...) too tightly, then it can stop the treadmill from working or running. An over-tight treadmill belt can cause wear, or even damage, in many other ways, such as by overheating the motor.
So if it only stops after 5 minutes, it might be owing to the belt being too tight, straining the motor, and overheating it or circuits to the point where it shuts down protectively.
I hope it isn't worse. But try that, and see whether it helps. Let me know, in Reply To Expert, so that I may close the case, or give you further advice, as appropriate.
Readjusting the tension would be vital in the short term.
I am looking up the info requested and will post again in 5 min.s or less.
Here's one with a cost up-front (before S&H and/or tax) of less than $5:
And here's others:
for less than $5 up-front price, and there's
for about $25.
...and also, here are these instructions from ProForm themselves on how to apply the lubricant:
