Hello

I have a Holley Sniper 1 i sold to a friend and has been on his 79 Z-28 for a while now without any issues until we installed a stroker 383 and added an MSD 6AL-2 with a blaster 2 coil and pro billet distributor and now it ran great for a few days an it now cuts out randomly and the display says "no data" on every sensor but then it resets instantly except for one time it wouldn't so i disconnected the battery for a few minutes and it came back to life.

Anyone dealt with this before and have any ideas on how to correct it??
