As or "what do I do"

How do I need advice or tips to fix my voyaguer 97
Failure after turning it on 30 minutes avess turns on later and others after one day I already changed ignition coil; crankshaft sensor and even the computer already checked the fault presents it circulates or stop at the same time. I appreciate your help in advance

The check light turns to you? or is it abrupt, do you stop and now?

Hi Kikemec First thank you for your attention, I do not set the check just turns off either when it goes in speed or when it is cut suddenly the current as if it turned off the suich falls all the abuits of the board and how I told you sometimes turned immediate fails if there is fuel but there is no spark in any spark plug

mmmm. Well, if it is rare, reconnencing everything you changed already because I have no idea what it could be, but it would not be good that you checked the alarm, since it could be involuntarily activating, well it is just an idea, although you already put me to think, hopefully some friend Forero can help you more (Kikeme has good ideas) but it would be fine that you put us high since with these faults we learn a lot.

Another thing that I need to comment is that I believe that the problem is non -mechanical electric, but well hope someone to provide some solutions
