The other day i was driving my truck and all of a sudden it started to slow down and thre bettery light check oil light and the service light all came on at once so i pulled over and of course it didn't want to budge so i went back to get it and i tried starting it and it worked so i drove it and no more then 3 minutes later the truck did the same thing someone told me that it might have been the fuel pump so i changed it but it still don't work do you think it could be something else or i just did something wrong if u have any input please help :smokin:

Might be the alternator going bad. i had that same problem with my '93 bout new years frickin night. take it up to almost any auto parts store, Advance, O'Reilly's, Auto zone and they can check that and the battery for free.
