My V-amp pro will restart(sometimes) while at rehearsal or at a gig. The fuse is good. Would the battery cause this? I have thoroughly checked all connections, resisters, capacitors, diodes and they all seem okay.It's puzzling

. It will shut off then come back on, there's about a 10 second delay, it happened last Sat twice during a show, so I just used my Ampeg without the V-amp. Any ideas? Bought used, so no warranty. Thanks, Deano
