whatwhatwhattt

I experienced the power cycling issue for the first time last night at band practice. I'm running firmware 2.04 . Unit worked perfectly at the gig Saturday night, no damage or issues, but it was so bad at band practice last night that after trying four different outlets I gave up and powered it off.... now seems to be working ok today. Upon power up, the unit would flicker the lights quite a bit, then display random colors, text would disappear, pedals would not function, then the whole thing would power off after about 3 seconds, start up again, and repeat. Seemed like handling it and moving it around caused it to last longer before it shut down. Effects worked fine while it was on, no nasty sounds. I pray this does not happen again during a gig... but how can I be sure?
