on. What could be wrong with it?

Runs great no codes..just replaced spark plugs...cleaned throttle gate and replaced the air filter. When starting for the first time that day it will start with no problem but will idle back and stall out..If you hold the idle at about 800 rpm and count to maybe 30 ...idles great for the rest of the day.
Any Help will be appreciated

It does the same with all lights when the engine is running, its not the alternator, seems there is an electrical load or short, this happens for about 5 seconds every minute.

had JUST had tune-up done--next day, #'s 1 & 4 ignition coils go bad. Had that fixed now the car will run for 10min then shutdown and will not start. The engine will turnover but no start. But it will start after sitting awhile. Eyes new fuel pump that was not it. When spring fuel in throttle body it will start. so what will make the fuel pump run but not reach the fuel injectors?
