Problem starting truck

I had this problem once before, with an older model Chevy Blazer. My truck kept stalling and would not re-start until 10-15 tries later. After seeing 5 mechanics, we finally learned it was my distributor! Now I’m having a similar problem with my '97 Chevy Tahoe. Before I take out the distributor, does anybody know how to determine if it’s the distributor or (what I believe) is a coil that’s bad? Or has anybody else had a similar problem with their Chevy Tahoe that turned out to be something entirely different? Please help.

If you don’t know what is wrong- throw parts at it! Maybe you need a new kitchen sink.
