Engine turns over for up to 15 seconds before starting on 1998 Nissan Maxima

Lately, on the first startup of the day this has been happening. If i have driven the car in the last hour or two before the startup, there is no issue. When it gets to be 3-4+ hours, the engine will turn over several times with the clicking of the dash lights before finally starting up. I'm worried that it's going to burn out my starter if the problem persists. I'm not sure if this is related, but sometimes the car squeals for a few seconds on startup also. Help would be much appreciated

the fuel pump sounds like it is loosing its prime. have the pressure checked after leaving overnight to verify.
