I just had something similar happen to me. Last time this happened, I had a blown head gasket that would not make it hot. It kept fouling the plug out.

This time, It was a hookup off the injector. Its clip was broke and after I zip tied it, it worked. Try checking the all wiring then move to spark plugs. Then move to coils. IMO.
