My current sbproj consists of a simple ODE model in which 2 molecules need to be present in order to yield the product molecule. Currently the model is running with an initial concentration for one of the molecules and a dose for the second molecule at time = 0 with no errors. However, when I set the same dose at time = 5000 seconds, I get an error when I simulate the model (Integration Tolerance Not Met). I have tried to set the absolute tolerance to a new value but did not work.

Can you attach the project so we can reproduce the problem? Also, can you share the output of ver or share version info for MATLAB and your operating system?

Without reproduction steps, I can't be sure what's going on. I recommend reading this page on Troubleshooting Simulation Problems. I'd probably start by turning off AbsoluteToleranceScaling to see if that makes a difference.
