Arduino nano randomly resets- and requires new program to recover. Weird, right?


has had occur?  haven't seen myself , haven't assessed units claimed happening on, hoping there , check out  myself soon.  want armed relevant knowledge beforehand though if possible, here am.

i built 20-some prototypes turn on ssr regulate heater.  working pretty (especially considering shoddy programming skills).  2 of them have started "erase program" after time running.   this client's assessment not mine- assume behavior isn't possible, says when plugs module, lights normal, there no status on serial monitor (and there should be- part of program).  can "fix" re-uploading program board, , operation resumes normal.

anyone heard of or similar behavior?   thanks help!

do resume functioning if they're powercycled? if they're manually reset?

capture failed unit , read out contents of flash via icsp - see if there's difference between what's seen there , what's on working unit.

is power supply stable? there glitch on power rails?

if can, post schematic examine.
