Starting problems with a 95 Subaru

95 Subaru with 184,000 miles. Just had a new starter put in as it was not starting on a consistant basis. Still not starting on a consistant basis. When it won’t start, I wait 5 minutes and then it starts with anywhere between 1-3 tries. I’m worried that the “5 minute rule” may not work sometime and I’ll be stuck. Appreciate any suggestions.
