Electrics seem fine, and the car will start pretty regularly, but at times it decides is won't. I can hear the electricity flowing, and everything inside turns on. Has a brand new starter, just changed the oil and had the transmission fluid filled. Its running ok, except for a random check engine light that comes on for ~5mins a day. When the car won't start, there are no warning lights on, but the gauges move and everything else works fine.

I am thinking it may be the starter solenoid, but would like to double check.

Thanks guys.
