Hi, jjcantarella!

Since your question has to do with a heater rather than a piece of furniture, I've moved it to this forum topic area where it will be more likely to be noticed and addressed by our Heating & Air Conditioning Experts.

Also, I did need to remove your email address from your post. Once a thread has been started, it's important that all information stay on the thread so that others with similar question can benefit by the information that's exchanged. I also would hate to see you get spammed because your email address was exposed here.

Thanks!

Exact model #? NatGas or LP? If ignition cycle(s) are so brief, possibilities are somewhat limited but more info will help streamline even further. I would make sure flame sensor & main burners are clean, and check gas pressure, for starters.
