A client complains (I cannot look on it at it happens as I am not on site) his Internet is goes down for a few seconds during the day with no pattern I can follow, as wall sometimes start working slow for a short period of time her and there during the day but no pattern I can follow.
Is there way with Wireshark to find the issue?  Would this be the right tool to use?

I would start with Colasoft ping tool.

Is it WIFI?
Maybe try put in a cable if possible.

It mostly sounds like a problem with the clients device. But more info on the actual network setup could be nice.

Have you asked the ISP to reset their network device?  Often helps.

It's all computers on the network.

The ISP already took all steps to verify the issue is not from their side

If the ISP is not the issue, then look at your router and switches.

Try a couple of computers through a known good switch directly to the ISP modem.

If it is all the network, then it might be the main switch.

So you could also try to plug a device directly to the router. If that device does not seem to have any problems with pinging a WAN ip, then it must be your LAN.
Im not 100% sure im right.

Not really. Wireshark is a packet sniffer. It will trace packets from beginning to end but will not tell you if there is a problem in the middle.

It you have an outage, it won't sniff the packet, so you still do not know:  switch, router or modem.

I was having a similar problem this past week and I have Comm View (professional Wireshark) and packet sniffing did not help. In my case, the ISP needed to reset my cable modem from their end and all is well.

In your case, you say the ISP is fine, and all the computers cannot be bad, so it must be the network and you will have to resolve by process of elimination.
