The unit runs for a few minutes and completely...

Question

Plug it in and turn the t-stat on. The fan inside operates as does the cooling components. After a few short minutes the unit shuts down (including the fan inside). Now it will get to temp but still it shuts down. I removed inside panel to veify fan operation and fan shut down. I have to turn the t-stat on and off a few times before it will re-start but the same episode occurs.Hmmmmmm ant thoughts?
