The only advice I can offer is to find a reputable repairer to take a look. Costly I know, but probably worth it in the long run.

You have a short, it gets hot as its running overloaded due to the short, and the thermal safety cut-out is kicking in. Once its cooled again the thermal safety cut out resets and you can play agin.
Needs professional servicing to locate the short.
If its a valve amp this could be particularly dangerous. Not to be attempted by the uninitiated in the pwer of electriccery. Seriously.

Whats the amp?

Mine too, not every 5 minutes though.

Reckon it's joint problems on the inards when it warms up. The heat expands all the joints probaly causing a break in the circuitry.

As someone earlier said, take it to a tech who can follow circuit diagrams. My amp is a Trace Elliot for reference.

Hi I repaired a trace recently which had this problem. It was the cooling fan. The fan should run continuously. If the fan is not running its either the fan is faulty, or the cicuit which drives the fan and controls its speed as the amp gets hotter. Your probably finding it cuts out when its being pushed at proper gig level rather than playing quietly at home.
Hope this of some use
