Will not start

What was in my truck I stopped to do something and put it in park and all the sudden it started bogging out and then it shut off. After that I tried to crank it over again but it wouldn't start. All the fuses and relays are clicking and doing what they're supposed to do. The lights are coming on when I turn the ignition key to start the engine all the lights go dim as if to send power to the starter to turn the vehicle on, but I don't hear anything else after the relays click a couple of times. When I was trying to crank it over it actually turned on but it just seemed to keep cranking over and cranking over it and then it stopped and now it does nothing but the light still come on.
