I don't believe a UHT is only getting temps up to 80f, I've used one unstated to see how high it gets and it goes around 100f. This could possibly be the cause of death! Remember to use a digital thermometer as well, of course, as analogue won't measure the temp of the mat and just the ambient air temperature. Also, never heat a tank on both direction (UHT and heat bulb on top) Heat should only come one direction or it may confuse the frog. Finally, a thermostat is a must with UHT, especially for burrowing animals.
the mat was actually a hermit crab mat. it produces way less heat than one designed for frogs or lizards. i went with it so i wouldn't burn him. the thermostat is placed just above the sub so i m temping very low in the tank. i also had a 40w buld on 12hrs a day while the mat always stayed on. i placed the water and soem moss directly over the heater to prevent the frogs from borrowing directly above it to above burning them as well.
