Hi and welcome to JustAnswer; a Q & A site and I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.

Initially, let's try check and review the basics. Proposed preliminary tries (if have not been done):

  • • when the Raptor "...cuts right back off...", cautiously perform a spark test;
  • • drain the carb bowl to determine fuel content's quantity and quality.

The above would help point to whether the issue is electrical/missing spark or fuel starvation/delivery.
