my van won,t stay running new starter and new alternator

What is your question?

i was in a wreck last year and bought a new starter last year and this year a new alternator and i can still drive my vehicle but when i start it wants to die on me and i can only go six blocks with my van it don.t leak or makes noise it just wants to die in the middle of a road or stop light I need a starting point to find out what is causing my van to not want to stay started.

What makes this problem better or worse?

yea both way

How long has your 1997 Chevrolet Astro had this problem?
