I have been having some problems with my car, can anyoine help diagnose the problem?

It just got a new computer a month ago, it was shutting off randomly, kinda wierd. It went in the shop, they replaced the computer, some sensors, the water pump, and i think the alternator. Then tonight my battery died... anyone have an idea... if not anyone can take turns beating it with a fucking sludge hammer
