yup, friend of mine toasted a brand new MSD last week while dynoing the engine!!!! Pretty much the same symptoms as yours. He was running an MSD 7, what was yours??? I had a 6AL, sent it back to them 3 times and never did have it work right. Don't know what system I'm going to get next, but it WON'T be an MSD. Way too much money for all the grief. Never seen a good warranty get me to the next round.......
