YEs, it does sound like a thermal problem...

The normal way to troubleshoot this is firstly to check all the obvious
conditions when it locks up (power supply voltage(s) being top of the
list), and then to use freezer spray to cool chips one at a time to see
if you can find one that iwll let it restart, or to use a hot air gun to
heat chips (carefully) to see if you can find the one that locks it up.
