2000 Chevy Blazer 4.3 - Runs & Drives great MOST of the time. Ocassionally without warning will not start, getting no fuel. Replaced pump & all the normal fuel issue parts. Gives no code when problem occurs. Had SEVERAL Well respected shops try to solve problem (After Many $'s) with no luck. After car starts may be several weeks before it happens again. This has been going on for 2 years Any Suggestions

Check for loose connections. The fuel pump relay could also be faulting intermittently.

Have already checked all connections will replace relay.
Thanks

BTW: It did it again lastnight, used gas thru throttle body.
Would run until gas burned out & die again, did this many times with no success. Walked out this morning and it started as soon as I turned the key.

Find a parts store like Autozone or Pep Boys that loans tools and borrow a fuel pressure tester. When the problem occurs, check the fuel pressure at the regulator. This sounds suspiciously like a condition known as vapor lock wherein the fuel in the fuel lines boils.

Motor is always cold, usually happens after setting all night or all day. Can this still occur with cold motor?

Vapor lock with a cold engine is almost unheard of. It requires heat to boil the fuel into vapor.
