Now at 1800 boot count with no issues. Hardware is stable.
Secondary, intermittent reset issue seems to be solved by properly marking ISR routines to be copied to SRAM.

//=======================================================
// windTick: ISR to capture wind speed relay closure

void IRAM_ATTR windTick(void)
{
timeSinceLastTick = millis() - lastTick;
//software debounce attempt
//record up to 10 ticks from anemometer
if (timeSinceLastTick > 10 && count < 10)
{
lastTick = millis();
tickTime[count] = timeSinceLastTick;
count++;
