Hello and welcome to JustAnswer!

There are several things that will cause a loss of spark and it's going to take some electrical testing to determine what is going on. It could be a sensor issue, the engine controller itself, wiring or cam timing.

The first step in diagnosing the problem is to use a scan tool to see if the engine controller communicates and if so what fault codes are set. Do you have a scan tool?
