Chevrolet: 94 lumina van ignition control, lumina van, couple problems

Question
    I have a couple problems with this van. First, my engine light was on and it was using a lot of gas and not much for power. I had it checked at the shop and they said it was the ignition control module. I replaced that and it smoothed right out and ran great, for about 30 seconds. It died and now it won't start.
    Also, my lights seem to have a mind of there own. Sometimes, they just go off, about a minute later they will come back on. Could this be in the switch? Any help would be greatly appreciated. Thanks, Leroy.


Answer
Hi Leroy;
       I would take it right back to the place that put the module in ,if they told you it was that I guess that they have a computor and it should tell you the code of the trouble, is the map sensor bad ? and as far as the lights the switch sounds as if it is bad. OK
