car starts and dies... why???

so i don’t know what is causing this… but sometimes when i’m driving my car… or just started it for the first time of the day… and turn it off a couple minutes later… and than i try to restart it, it will start and die right away…and then it will just sit there and crank… i don’t know why it’s doing this and would really appritiate it if someone could help me… has anyone ever had this problem before? usually when it doesn’t start… if i leave it alone for like 15 minutes and try to start it again it starts right up and drives fine… this problem is making my car really undependable and i’ve tried tons of things to try and fix it… PLEASE help anyone! Thank you in advance…

anyone? could this problem possibly be the main relay? (MFR)… i did the solder trick on it… could i have possibly messed it up?


There are more solder posts to inspect for cracked circles, I soldered a couple of my posts but learned later of the posts in the above picture.
