ODE solver not running full time span

I have never encountered this issue before but I am solving a large system with ode15s and have specified a tspan of 0:0.01:360 but the solver is only outputting solutions up to t=321.6. I'm assuming there is a numerical issue but the solver is not outputting any error. Has anyone else experienced this and found a fix?

That suggests to me that you should have received a warning but perhaps you've suppressed it? Something along the lines of "Failure at t=321.6. Unable to meet integration tolerances without reducing the step size below the smallest value allowed (some_small_number) at time t."
Did you turn warning off in your code or turn off specifically the warning with identifier MATLAB:ode15s:IntegrationTolNotMet?
[Fixed warning identifier to refer to ode15s not ode45.]
