I'd suggest enabling NAT-T on these and make it send keep alive packets to avoid that.

When you say tunnels, how long are your rekey timers? What you could do is set a extremely long phase1 and phase2 timers for the SAs.
i.e all of these settings can be done from CLI
ph1
172800 /* that's max value in fortiOS 6.2.4 do not think it has changed of the last few years
set keylife 172800
ph2
86400
set keylifeseconds 86400
set keepalive enable
And they monitor? Keep in mind DPD if used, is going to tear down the tunnels if it indicates a failure. So if your remote-vpn stops sending traffic and the higher up IPSEC-SAs times out and no auto-KeepAlives your tunnel will died.
And lastly be aware of DPD support and lack of in the forticlient if that is your dialup-ipsec-client assuming we are talking dialup vpns. Difference types of vpnclients ( windows vrs macosx ) and version seems to play a big part if DPD does work or not.
