Ignition Module

My 1988 Chevy blazer 5.7 350hp keep blowing the ignition module about every 2 years.Now it blew 2 since Sept.
Has anyone come across this problem???

Thanks,
James

Improper installation with out the white greese.
Cheap white box modules.
High voltage restiance on secandary ign.
Poor connections.

High resistance in the ignition coil primary windings can also cause the module to burn up prematurely.
