Hey,
Are you saying that it is re-lighting the gas or is the fan just coming back on?

Hello: banditowner

Sounds like there is either an intake air restriction or an air flow restriction. Check the filter and open all registers.

If the unit also has A/C, the coils could be restricted with lint and dust.

Hey,
If it's not igniting the gas, then it could just be your fan switch setting.
