KK......my buddy and I both use line 6 amps but we were playing at a gig that hosted 4 bands last night.
First band that went on were using my buddies combo spider 3/150 stereo amp.
band went on,did their thing for 45 mins and left.
my buddy went onto stage to do his stint.turns on his amp,lcd lit up as normal and could hear the speaker kicking in,it stayed on for around 2 secs and just shut off.
Also,this amp wasnt overheated as from the time the previous band had played,until he then switched it on,the gap in time was maybe an hour.
he really isnt happy today about this!
