I have a Delta three handle shower system that was dripping water for a few days and then suddenly became a steady stream. I've replaced all of the valve parts from spring and boot to faucet parts. I have assembled and re-assemble everything three times. Every time the water does not drip at first and them after first use the stream comes back. Issue has alternated from hot to cold water valves.

I have also tried stretching the springs for more tension with the seats.

Totally at a loss. Any help or suggestions would be greatly appreciated.

I suspect debri or sediment/hard water buildup, and maybe cleaning the stem seats is what's needed. Review this from a Delta faq/customer support,

FAQs : Customer Support : Delta Faucet

First, we need to find out if the hot or cold valve is causing the leak. Let's begin by troubleshooting with the hot valve:

Shut off the hot water supply. If you can't find the shut-off for your tub/shower valve, shut off the water to your house by using your water shut-off valve.
Remove the faucet handle. To do this, depending on your handle type, you will need a Phillips screwdriver or an Allen wrench.
Remove the chrome bonnet nut using an adjusting wrench.
Remove stem extender.
Remove stem assembly by pulling straight out.
Remove the extender and stem assembly.
Remove the seats and springs.
Examine them for wear or debris and wipe out any debris in the depression where the seats and springs sit in the valve body.
Replace the seats and springs. (Delta Genuine Part RP4993 -€“ two sets per package).
Reassemble the faucet to see if the drip has stopped.

If the drip persists, repeat the above steps on the cold valve.
If you've replaced the seats and springs and the problem continues, replace both stem assemblies (Delta Genuine Part RP1740 - one stem assembly per package).
If all of the above has not fixed your leak, and your valve is more than 10 or 15 years old, it is possible that the actual faucet body may have developed a leak. If so, you will need to replace your tub/shower valve with a new one.
Note: Consumer safety is our number one concern. If you do not have experience with plumbing repairs, we recommend that you contact a licensed plumber for tub/shower repairs.

Let me know if this helps or NOT.

Thanks for the tip.

I cleaned out guts of the fixtures and reinstalled everything. Same issue with no dripping when the water get turned back on to the house and a steady stream after the handles to the fixture are turned on and off again.
