farmboy with an 01 international having problems

sup yall's we recently purchased an 01 international with the cummins motor. (has 3 individual heads) beyond that im not to knowledgeable since this is my first semi. the other morning i fired it up to move it out of the way while we started harvest. it fired up just fine ran for about a minute and a half and shut off. i've tried firing it up a few times and it just cranks over. i replaced the fuel filter and used these rubber caps to prime a the pump im guessing (its what i was told to do) and i still get nothing. when i turn the key on and the gauges set themselves the volt meter reads at about 10.5volts but it turns the motor over with no problem. im wondering if its not enough power to run the computer system possibly? anyways i really appreciate any input that would help me out. sorry for being the NOOB

there are no lights that come on when you have the key in the run position. after you put it in the run position it beeps at you for about 15 seconds. the battery terminals look like they could use a good cleaning. there isnt any corrosion build up or anything but they arent the cleanest lookin batteries i've seen. i didnt look to see what the voltage does while cranking. ill check that tonight. where is the ecm located. i see all the fuses.

 

well we cleaned the batteries and it started and ran for about 3 seconds and shut back off. ill check the cables at the starter tomorrow. i know there was one with with an inline fuse in it at the glove box. ill check them out and see if i can get a couple pics.

also the low fuel light came on but the gauge says half tank and i know theres plenty of fuel in it
