Did this problem just start all of a sudden since you have had the machine for a year? Have you installed any new programs or updates. You should not have to wait 5 minutes to turn the machine back on - you can turn it off and right back on.
How large is your design? Are you having trouble with everything you are cutting? Have you tried different files to see if it happens in just this one or in all of them? You don't have to waste vinyl testing - just use copy paper or light cardstock and test cut a few things and see if it goes into pause.
If it is just one file that is causing you problems you can upload it here and someone can test cut it. I can't right now because I just moved and my machine is not connected yet
But there are plenty of others who would be happy to give it a try....
