What seems to be the trouble? Having trouble starting could be a number of things, but it's likely a safety switch or loose wire somewhere in a new tractor like yours.
Unfortunately it sounds like a wiring issue with heat being the culprit, or a fuel pump thats pooping out after a little run time. There are some good Case IH dealers in your area with great service centers. Sievers in Hamel IL, Ennis in Troy Mo are likely the closest.
