Default mustang dies at startup

89 mustang gt conv. specs are below. in the morning, every single morning i start up the car and it idles real struggle like, and actually turns off. for example the car starts, idles up a little then bog bog, then the car boggs out, all within about 2 seconds, only does it then. if i give it some gas as its struggling then it still struggles for a secondand doesnt turn off that way (but my radio setting are reset on my headunit, as if it kills the battery for a split second....thats how the setting get reset usually)......then its ok the entire day, i can turn it off and on no problem, its only that initial startup in the morning that makes it bog out and die a couple seconds...what could it be? i just got my injectors cleaned and fuel filter changed and it has been doing it before i got that done, but its like it does it worse a little at a time, i mean its in order, 3 months ago it barely dropped under idle RPM, 2 months ago it was almost bogging out, now it is. battery maybe? alternator? i got the car used about 11 months ago and same battery, its a good battery, no clueon the alternator...but my batterychargeIS a little low........so any help would be great, thanks

check all ground connections and terminal connections for looseness and or corrosion...also have a battery load test performed along with an alternator test to eliminate the elec system

Clean your battery terminals and the wire clamps really well and try it again.
