Will not start?

Replaced the starter ignition switch battery and battery leads. I drove it all day and as I was pulling up to a gas pump it shut off. It hasn't started since. All lights come on but when you go to crank it sounds like it is losing power or not getting enough juice even when jumper cables are connected to another vehicle. After about the third time the battery is empty and makes that fast-clicking sound until nothing. I've done an OBD2 reading, and it came back the Skim or Skreem module, but I'm not sure.
